costco?.........dont you have to get an annual membership at that place?
yeah, you do. that said, 4oz of redstar active dry yeast is $7.49 at my local safeway, which comes out to $59.92 for 32oz of yeast. the basic costco membership is $45/year; plus, you could probably find other cheap stuff there, if you don't mind buying in bulk. or, if you have a friend that has a membership, you could always ask to tag along when he or she goes to costco, and then buy it on his or her card. somewhere like smart and final (which doesn't require a membership) may also sell yeast for a relatively low cost as well. in my (extremely limited) experience, the supermarket is the last place to buy yeast, assuming one wants to save a bit of money. you could also try looking around online a bit. earlier today, when looking for a picture of the package of red star yeast, i stumbled across http://www.spiceplace.com/product_info.php/products_id/25
. $5.49 for 32oz of active dry yeast is still a good price, i should think, though i have no idea whether they'll stick it to you in shipping or not.
