Free: Contests & Raffles.
I use the Alaskan bags as well, I got tired of ripping. I don't pack them around with me though, I just go back for them if I get something down, I use that trip for getting rid of most of my gear anyway and then grab my pack and bags for the trip back for the animal. Its one more hike but I combat that by cutting back on the beer the month or two before the season starts.
plain white sheets, cut them up make your own bags.. bleach them after use and your good to go for years.....
