I bought a Country Living sheet set. After one washing, there was a big tear in the pillowcase.
I had not kept the receipt because I simply did not anticipate the need to return a sheet set. The store refused to take them back at even the lowest clearance price, or give me a store credit. I have had similar experiences at Sears, and will not be going back.
In the past, I returned a toaster oven for repairs.
After being told that the item was ready, I went to pick it up, and found that it still did not work.
