Just looking for some opinions really. I won an item on ebay yesterday and the seller messaged me to say she would post as soon as possible due to the snow, she seemed nice and friendly and has good feedback. However she has sent me another message this morning to say she's just posted the item this morning and it cost far more to post than she had accounted for. She has put a photo of the receipt. For reference she charged £5 postage and it actually cost £13.95 as it had to go with parcelforce rather than royal mail. She is asking for the extra postage. I do feel bad but I also think she could have sent it with my hermes or similar and it wouldn't have been much more than she charged. She has still made a profit. What do I do? I was thinking to wait until the item arrives and make sure it is as described etc and then offer to pay the extra. In the past I have undercharged for postage and have never asked for any extra I have just accepted that it was my mistake. Just looking for the general opinion in this situation.
