Ever since Hostess went into Bankruptcy (again) earlier this year I've had a heck of a time finding my Hostess vice; Coffee Cakes. Not those 100cal posers either but the ones fully covered in cinnamon & sugar!
Then when I could find them, I'd buy 2 or 3 boxes at a time but they just don't last. So I'd say if you want to remember the fresh taste of Hostess, eat them up sooner rather than later if you're going to stockpile.
As was said previously, I just don't see some of those products going away. Some company will buy up the rights but it could be that they are just too expensive to produce with the costs of raw ingredients going up.
Oh and I was all like 'stupid Unions' too until I read about how poorly the Company has been managed over the last decade. It's no wonder they went out of business.
