I sold my first racquet in September, a really nice 200g. It was a good deal. The buyer dropped me an e-mail, and the money was in my Paypal account almost immediately. I assumed I would get a reference, but he never told me his ID, and I assume now that he wasn't a member. I have no problem with selling to him, but since I'm likely buy or sell only a couple of racquets a year, getting a few references is meaningful. Do sellers usually ask for member IDs before shipping?
