Unless someone can provide proof of this series still being available in retail stores, I recommend that it be listed as discontinued. I haven't seen any available in a very long time now except on eBay or Amazon. If I'm not mistaken, these were only sold for a short time in stores.
The whiteout series is not contiued. I jsut went to 3 walmarts and there were whiteout Deply's,Longstrikes,Nite Finders,And Maverics.
The Walmart stores in your area must have found some old stock, because Hasbro has verified that the only colored series still being produced is the Sonic series. Next time you are at one of those stores, be sure to get a picture of this large number of Whiteout series blasters and post it here. Better yet, buy them out and you'll probably at least triple your money on eBay. They wouldn't be so rare there, and going for outrageous prices, if they were still commonly available in most stores.
