How Specialty Retailers Can Uncover Pockets of Hidden Sales

One of the most significant advantages enjoyed by the large discounters and big box merchandisers are their economies of scale. By buying an enormous volume of commodity products from their vendors, they can drive prices downward on those items. As a result, the megastores can charge less for basic items than specialty retailers can profitably charge.

Having said that, independent shop owners can find their opportunity in niches. If online retailing has made one thing clear, it is that consumers will easily gravitate toward products they want to buy if they are only given the option. Below, we'll explore the long tail of retailing in the context of how small shop owners can profitably cater to niches.

Using News As A Retailing Model

To lay the groundwork for this discussion, consider the evolution of news distribution. Years ago, there were only a few channels through which you could receive the news: newspapers, network television, and radio. To be sure, consumer choice was severely limited. Today, in addition to those choices, people retrieve current events from cable television, blogs, and thousands of other online sources. In effect, the number of choices from which consumers can select has grown exponentially.

Many of these news sources cater to specific demands. Some are conservative and others are progressive. Some offer a broad swath of topics while others provide updates on certain industries or sectors. This is a perfect model for the future of small, independent retailing. Local merchants need not compete with mass merchandisers for a share of the market on basic commodity items. Instead, they should carve a niche for themselves.

Why Independent Merchants Should Carve A Niche

With the debut of online properties such as Amazon, eBay, iTunes, and Netflix, consumers have grown accustomed to having access to niche products. Were they to buy a package of paper towels, any brand might do. On the other hand, their tastes in books, movies, electronics, and hundreds of other retail categories has expanded into specialized areas. Therein, lies a small retailer's opportunity.

Independent merchants can more easily attract a loyal customer base by catering to niches that are underserved by the megastores. For example, an astronomy enthusiast may be able to purchase a telescope from a mass merchandiser. However, the selection of mounts, eyepieces, and different optical designs will be severely lacking. By contrast, a small retailer who specializes in that niche can better accommodate that market.

Limitations Of Inventory Management

In any physical retail setting, merchants must cope with limited cash flow and struggle with efficient inventory management. After all, there is only so much cash and floor space and both must be used productively. Meanwhile, having cash flow tied up in merchandise is a balancing act; there must be enough merchandise held in stock to satisfy customers without unnecessarily tying up limited resources.

Catering to a tightly defined niche makes cash flow and inventory management simpler. The wide variety of assortments are targeted to a similar audience. Average ticket prices increase, customers return more often to purchase additional items, and if demand is forecast properly, inventory turns over more quickly.

The Value Of Long-Tail Retailing

What I've described above is not to suggest niche retailing eliminates the need for tight controls. You should still keep your inventory as lean as possible, negotiate favorable terms with your vendors, and watch your cash flow. Furthermore, you should avoid sporadic expansion into unrelated assortments (unless you have identified a clearly defined demand) and focus on providing the best experience possible for your customers.

That said, long-tail retailing is a strategy to leverage the growing trend toward specialized niche products. Small retailers can use that strategy to avoid competing with the big box merchandisers on commodity items.

Orion SkyQuest XT10 Classic..... Need some Help Please!?

Is that telescope big enough to see alot of deep space objects? What all DSO can be seen through it with a 10mm eyepiece? How do I locate objects in the night sky??? Im having problems finding stuff in my telescope.. I found saturn, the orion neb... & the moon.... thats all.... What all can I see in it? Is that telescope a good one or did I get ripped off???

Your scope will gather enough light to keep you busy for years observing. But the mount itself is fully manual, so you'll need to learn your way around the sky to find things.

Get yourself some nice star charts. Sky & Telescope publishes a nice one that's not very expensive. You can also look for sky information on line.

Here's a link to one - you'll need to give it your longtitude and latitude to get an accurate map:

< http://www.fourmilab.ch/yoursky/ >

Next, forget about the 10mm eyepiece for locating objects.
It's got too much magnification for a beginner to use to hunt things down. (higher power means you see less sky at once) You can use it for observing objects in greater detail after you find them.

Get yourself a nice wide field low power eyepiece. Something in the range of 30mm would be good.

If it's in your budget, I suggest the TMB 30mm Paragon eyepiece. At $250, it's a significant investment, but quality eyepieces are a lifetime investment.

If your budget is more limited, look for a 30mm eyepiece that has a 2" diameter barrel. A good resource for telescope information is the forums at:

< www.cloudynights.com >

Otherwise, see if you can find an astronomical society or club in your area, visit them, and consider joining. The dues are typically quite reasonable.

Good luck, and enjoy.

The Barska Blackhawk 60mm spotting scope is a terrific value because it offers very good optical performance in a compact and affordable package. The scope itself features waterproof design, multicoated optics, and a zoom eyepiece with magnification ranging from 20X up to 60X. The accessories include a light weight table-top tripod, a soft caring case, and a durable hard shell case that will allow the rubber armored scope to stand up to a lifetime of use. The Blackhawk 60mm spotting scope uses a multi-coated objective lens and rugged porro-prism design for bright, clear images. At 100 yards, I can clearly focus in on a target, even when I crank the magnification up to the maximum 60X. When I use the scope for wildlife spotting, the sweet spot seems to be about 30X magnification; 30X gives me an ideal combination of sharp images and a wide field of view, perfect for identifying Puffins and Pelicans along the coast. I also like the compact size and light weight of the Blackhawk 60. At only 14 inches long and weighing less than two pounds, the Blackhawk 60 is light enough to use a photo tripod such as the SLIK U-9000 in the field. Like other entry level spotting scopes, the Barska Blackhawk 60 uses an Achromatic objective lens, which means that some false color or blue fringing is noticeable at high power. I&rsquo;ve been pleasantly surprised by the quality and value of the binoculars and spotting scopes imported by Barska the last few years. The Barska Blackhawk 60mm spotting scope simply offers very good optical performance for a very reasonable price. --Jeff Phillips Pros: Excellent price/performance ratio Very good Achromatic optics Waterproof design with rubber coating Premium hard shell case included Cons: Blue fringing noticeable at high power Limited eye relief for eyeglass wearers
