Our Walmart has great selection and great service if "Marilyn" is there. Otherwise, its a toss up. Everyone is very helpful, just not experienced. A very nice young mas came tohelp and was very glad to watch "me" measure and cut. He confirmed it all and I got what I wanted. My last visit I was buying Wonder-Under and the end of both bolts, about 18 inches, were very wrikled and folded and she would not measure it, just gave it to me. I couldn't convince her that it was useable. Great service.
