I haven't had them for many years, so don't know what if anything might have changed, but I'd point out that there are a lot of companies that make competing...I think they're called "toaster pastries".

Maybe try one of them, see if they work? They should ship pretty easily, so even if a local grocery store don't have 'em where you are, I bet that they can be ordered.
