So ebay has a Make an Offer button which this buyer used and made an offer. I thought it was weird because it is the full asking price of the item but its happened before because sometimes they just do that when the sale is ending and they just want the item. I accepted and sent the invoice. She got the invoice and says I need to adjust it for free shipping because her bid was for the price and free shipping. I never got a message attached to the offer asking for free shipping but somehow when I look at the offer in the email in the ebay message system where the offer was accepted- it says free ship on the right side near my item but only her offer amount showing in the price. I charge shipping. It was in my listing and showed in my invoice. I don't know how she could have even changed the offer to free shipping because whenever I make an offer to someone - I don't have the chance to change their shipping - only offer a price and send a message if I want to. The shipping is $12 for this item and I don't want to have to eat it. If I cancel I'm sure she'll give me negative feedback. One of the reasons I really hate Ebay - how can Ebay allow certain buyers to offer free shipping with their best offers and not others and why aren't seller's even alerted? I looked at the offer and acceptance notification emails from ebay on my computer and neither one shows the buyer is asking for free shipping. I'm just going to tell her NO - I pay shipping so she pays shipping but I'll offer her some money off the item which I would have taken but not $12.
