Well anyway - the ones I found were around 4 dollars for 12 of them (which I know, is NOT cheap, But we got them from our pricey organicy food store, and everything in Alaska is MUCH more expensive so maybe they're cheaper in the lower-48). They're 13 gallon bags from a company called Perf. They claim to completely degrade within 2 years, which I think is fantastic - as long as they don't degrade in my trash bin! Dear BF took the trash out early this morning, so we already have a fresh bag in the bin, but the next one will definitely be this kind.
I just thought it was really great, and wanted to share the concept and see if anyone has heard of them
