I've been selling the odd thing on ebay for several years and rarely use recorded delivery.
Earlier this month I posted an item non-recorded mail to a winning bidder who's informed me that it has not been received.
Post office say that they will not investigate until 15 working days since posting (seems a long time for a parcel to linger undelivered).
Looking at the Royal Mail compensation form, in order to make a claim for loss in the post I would have to provide the original receipt showing what I actually paid for the item which is, by now, many years ago. I doubt anyone would have receipts for every small item they've bought over the years. I would also have had to have posted the item recorded delivery as otherwise there is no proof of posting - all the Post Office gave me is a receipt.
So, is it worth sending items by recorded delivery?
What do you usually do? I think I may have been a bit trusting by not using recorded delivery.
