If you look the seller has a pretty good record and not a newbee. I'd give it thru the weekend. The start of next week I'd start the process if he hasn't returned any messages on Monday. If he is a business, or if he has family it can take up a lot of time. Don't fret yet. Plus if you paid by paypal you should be covered. I know how it can be. The rush of wanting to get the item on the way. But relax. worry when you have to. Life is too short.
