Hi. I bought an item from a private seller last week. The item would be a small package to send and the buyer stated it would be sent 1st Class with Royal Mail. Anyway the seller only charged £3.20 for postage. Yesterday I contacted the seller as I still had not received it. The seller told me that the £3.20 did not cover First Class postage so therefore she sent it Second Class. Now I have been in this situation before where I haven't charged enough for postage but I have always sent it as advertised and just put it down to experience. Am I wrong in thinking she should have sent it First Class. I'm not going to make a fuss but am just interested in what you all think.
