In addition to the advice that has already been given, if the buyer never collects the item and you end up having to cancel the transaction then make sure that you add his User ID to your Blocked Bidders List so that he cannot repurchase the item if you decide to advertise it for sale on eBay for a second time.
If you are unsure as to how to add a buyer User ID to your Blocked Bidders List click on this link https://offer.ebay.co.uk/ws/ebay/isapi.dll?bidderblocklogin and add the buyer's User ID to the white box that appears on the screen. Once you have done that click on the Submit button beneath that box and the buyer in question will be unable to purchase anything else that you list for sale on eBay in the future.
