I won 5 items from the same seller. One was free postage and the postage for the remaining should have been £17. I had asked before the end of the auctions if the seller would combine postage and, yes, that was fine.
Seller sent an invoice stating an amount wHich I felt was fair - based on the cost of the postage for the items individually and not knowing what each item would weigh.
Parcel arrived today and I paid almost £3 over the actual postage cost and it was packed in recycled packaging.
Would I be unreasonable to email asking for a partial postage refund? If so, how do I ask politely? I'm crap at tactfulness!
