    I went to the store to return items. Despite having the original receipt, they said I had to return online or they would only give me back 50% of the value because items were now on sale. This is not stated in your literature. I wasted a lot of time doing this and now I have to waste more time figuring out how to return by mail and going to the post office. I don't think I should have to pay for shipping as well. This is a terrible policy that should be disclosed.
