The majority of snow blower manufacturers only make a set amount of snow blowers each season. Once they're sold, they don't produce anymore until summertime because they're making lawn mowers.
Large home improvement stores only stock up on as many as they project to sell, and rarely have any left by the time spring rolls around. They do this because they don't want any leftover stock that has to be discounted.
New snow blower models are usually introduced in May or June, but aren't being produced yet. However, you can back order a brand new snow blower before it's released.
By back ordering a new model of snow blower that's just been introduced, you tend to get a nice discounted price. You also get a brand new snow blower, which is arguably much better than settling for a used model that may have problems and that doesn't come with a warranty
Later, as winter is approaching, you'll receive your brand new snow blower at just about the same time as others are starting to shop around. You may be the first person in your neighborhood prepared for that unexpected early-season snowfall.
If you're interested in buying one now that's still in stock, you can find a better selection at Snow Blowers Direct than you can at a big box store.
