I was expecting a trainer mat to arrive today and instead I find an Ultegra/Mavic Open Pro wheel inside the package. I'm a bit ticked off because I really wanted to get going on my trainer this weekend and I really don't need a new wheel. What's my obligation in this situation? I'm always for "doing the right thing" but damn this is a hassle having to return it and then wait until they get my order right. If it's allowed then I'm tempted to sell the wheel, buy my mat, and pocket the change. Whatever I need to do, I'm going to do it tomorrow because I'm heading out soon.
