Query: cotton top full mattress pad

I ordered and received a mattress pad manufactured by Louiseville Bedding Co. This product is so inferior that I cannot believe that Amazon.com promotes the sale of it under their super saver shipping program. Considering that I can buy the same product at Walmart for around $18 but paid $30 from Amazon.com, I cannot help but feel that Amazon.com is charging for the shipping and perpetuating fraud. The pad shrank so bad that I am unable to get it onto the bed. Considering that the standard sizing for a full bed is 54X75 and this pad was 53X75 it started out smaller. I do not feel that it is fair to expect me to pay money to ship this back to Amazon.com and therefore I expect Amazon.com to send me a prepaid shipping label. Then when Amazon.com receives the pad I expect to get a full refund on my charge account.
