I have only purchased at Wal-Mart once. It was a slow process, but the fabric was cut properly. I went into my LQS a few weeks ago to buy backing for a top I had finished. There was a new clerk in the store and the owner wasn't there (which is unusual). The new clerk measured out the material I asked for and then snipped a small cut in the fabric and tore it. I was 18 inches shorter on one side that the other. I asked her to measure and cut it again. She said there was enough material there so I should just take it. I took the material and went back the next day and spoke with the owner and she cut the fabric correctly and gave me my money back.

I went in the other day and bought some more fabric and the "New" clerk cut the fabric instead of ripping it.
