I sold 3 items to the same person which means the postage was £8.05 instead of £13.98 as it would have been as separate sales. The buyer has messaged me asking me to transfer £5.93 to their PayPal. I think it’s cheeky to ask, especially as she didn’t factor in anything to cover the cost of the box, padding materials and tape. I had already packaged them as separate items to get the exact weight so I had to repackage and I damaged one of the original packages so I can’t reuse it. I shipped them as one item at her request. Do you think it’s just cheeky or is there a scam going on here and she will do something weird if I PayPal her the difference?
