*shrug* If someone offers me less than I want to sell for I say no, hopefully politely! Whether thast £1 less or £10 less than I am asking for. Generally I am advertising stuff at the price I need/want for it, ie my lowest price to cover fees, postage and the nappy so I dont often accept offers at all. I dont remember anyone being awkward with this.
Sometimes I will just pay what the seller is asking if its something I deem reasonable or I just REALLY want it, sometimes I make an offer if say I only have X amount in my paypal or such like. I hope Ive never made someone a 'mean' offer and I dont mind someone saying no
Most of the nappies Ive posted recently have cost £1.72 to post (or more, a nappy I received last week was £2.48!) plus fees of 56p on a £10 nappy so thats almost £2.50 on a £10 nappy going on postage and fees! Sometimes I think people can be a little forgetful of just how much of the money doesnt end up with the seller.
