How long to give buyer to arrange collection in person?

[BewareTheBeardedDragon]

I've sold something at the weekend - listed as collection in person only. The buyer is not particularly near me, and has not responded to my message giving my address and asking when they'd like to collect. How long would you give them to reply? I've got a horrible feeling that they didn't check where it is before bidding, and I really want it gone (it's big and bulky hence collection in person listing).

I would give them a week or so to reply - have they paid via paypal or is it cash on collection?
if they don't reply at all within a week, message to say you're relisting it, and relist it
