hahaha yeah dont blame on avoiding wal mart for that reason...
I got the great value stuff from wal mart... From what I saw, wal mart only had the actual Oxi Clean in a pretty small size, maybe 24 oz? It was like 5 or 6 bucks... They also had the Great value stuff for like 7 bucks... I will check on sizes tongiht but it was at least twice as big... So probably around 50 oz.
I should have checked costco... I imagine they would have the best deal.
