some of it is ok- some not so much; I was taught a long time ago to buy the best you can afford for what ever you are buying. if walmart is what is available- and is what is within your budget then by all means- buy your fabric there. with time and experience you will learn (by look and touch) differences in fabrics and find what you like/want to work with. don't stress over where it comes from- great fabrics can be found at Goodwill too! just buy the best you can find, afford, like.
