I will never buy anything from WalMart. A freind of mine used to work there, and he told me about the brainwashing sessions that count as 'training' (headphones, computer video 5 inches from your face, headphones, and every few minutes having to answer a question...)
I dunno - just not something I would want to support. Maybe ride my bike through their store yelling at everyone to not shop there... but never buy anything there,,,
