Thank you Birdy for sending me the link.
The seller has been a member of this forum for a while now so im sure there is nothing to worry about regarding being scammed, There may be a genuine reason why he has not been on here for a few days?
As stated above, hold fire for a bit and wait a few more days, it may be that that your item has been sent and you are at the mercy of Royal mail or the seller can only make it to a post office on weekends due to work commitments?
And as you have payed via paypal and paid fees worst case you will be able to file a claim, but i doubt it will come to this.
