Just left of normal

So i am one of those anonymous Walmart shopper.. you know those totally against everything that walmart is and stands for, the way they treat even their long term full time employees but most often financial circumstance rules out over even the atmosphere of Target. Sure i can get all those things at Target or the grocery store but my experience is that walmart is between $.50 to a $1 cheaper on most simple items and more on larger items, at the end of the receipt thats a significant savings to me. Though i get in and out as fast as i can and hope i don't run into anyone i know... usually i don't, that should tell me something right?

Anyway onto my point.. apparently for Earth day Faded Glory had a push of eco freindly shirts made from "100% Transitional Cotton - is grown using no chemical fertilizers or pesticides" printed inside the shirt it also says "by purchasing this product you are helping cotton farmers transition their fields from conventional farming to organic farming practices". So my question is, if a brand as big as Faded Glory can do it why can't they all switch? It seems like there is plenty of proof that natural and organic alternatives work just as well, in fact usually better, then why not switch?
