the caribou bags look pretty good, just haven't brought myself to splurge on them yet

I reuse the cheap bags from walmart/Canadian tire, $15/4 pack and have had my 2 packs for about 4-5 years now...I do a quick cleaning with the garden hose and soak in a bucket to get the bulk of the dirt off them, then wash them with bleach and detergent, double rinse, works good for me
