I didn’t realise that I purchased 4 small items from the same seller, and I paid 4 individual postage costs for these items. The seller decided to send all 4 small items in one small padded envelope and paid only 1 postage cost for them all. They did not message me to inform me that all 4 items would be posted together and give me the opportunity to combine postage costs for the 4 items. So I paid 3 postage costs for nothing and feel overcharged, what can I do?
