Unless the seller specifically stated in the listing that you could arrange for a courier to collect the item then you will have to collect it yourself. Should you be unable to do so then you will have to request a cancellation of the sale. If the seller stated "Collection In Person Only" in the listing and you sent a courier to collect the item on your behalf you would automatically void your eBay Buyer Protection and would not be covered in any way should anything go wrong. Therefore, collect the item yourself - that way you can inspect it thoroughly before you decide whether or not to hand over the money for the item. If it looks OK then hand over the cash and bring the item back with you; however, if you change your mind you can let the seller know there and then that you no longer want to buy the item and he/she can just cancel the transaction, after which he/she will be free to relist the item again.
