I have three of those, since I was in the right place at the right time and got two for free a week after buying one. If you like, I could send you one for just the shipping. And yes, they're at WalMart.

Thing is, they don't do as good a job as the actual vac sealers and they eat batteries like no ones business! Still, they're pretty good in a pinch, and we use ours for little things when we don't want to get out the FoodSaver. I would still recommend getting a vac sealer someday simply for the better job, but it doesn't have to be now.
