Ok, I finally won a few items on ebay (some vintage brakes and rear mech) anyway, It's been a week and I haven't had any contact from the seller. I paid through paypal the next day and have the receipt. Is this fairly normal? I'm new to ebay, so I just want to make sure I'm doing things correctly. Does one normaly get an acknowledgement that payment has been received, or does the item just tend to show up. I tried to contact the seller through ebay, but so far have no response. I'd hate to have an issue on my first transaction.
