People shop Walmart because the prices are low and affordable. And meanwhile, if you don't exercise diligence you could get garbage. I don't shop Walmart for many reasons, junk is part of it. So...in the case of fabric and pricing, why don't you go to either Hancocks-Paducah or Fabric.com and purchase the sale fabric? it's gorgeous quality, dependable and runs about $5-7 dollars a yard depending on how long the item has been in inventory.
And there really is no excuse about being "afraid" to shop online. The entire world is moving away from you, if you have failed to keep up with technology. In that case, you get to read the labels at Walmart and Joann's and hope you can pick a small piece of quality out of the garbage.
