I purchased a new handle for our dishwasher. It came and was the wrong size. Called them to either return it or get another size. I was told, sorry we don't return items under $30. What? When did I sign that? When I asked they said, it's in the return policy. Which I guess I should have read it more throughly. Many webistes have this policy, but do have some notification(usually in red) when you are checking out, that this is final sale.
As a business owner, I always disclose all before someone purchases.
