False... you don't buy good quality pants to look classy and branded... w/e that means, you buy them so you stay dry. Correct me if I am wrong but I am pretty sure wal mart pants don't come with anything above a good ol' 1000mm waterproofing.
Getting back to your question, check the Buy and Sell thread... sounds sketchy but you can usually find some really decent stuff on there for a good price, just make sure whoever you are buying from seems legit.
