well at this point, i filed a claim, and am waiting on paypal to make a decision. maybe i should have refunded her, but i've already paid $120 in just fees and shipping that would be my loss. maybe if she wanted a brand new bag, and is anal, she shouldn't have boughten a USED BAG!!
I am not defending either side. I do think that you should have at least given her a heads up that you would ship on Mon. I think communication is so important and I would have been just as disappointed as the buyer had I paid immediately. I bought from a member who didn't send out for nearly 2 weeks. I paid asap. Just simply using email to let people know what is going on, can save a lot of headaches down the road.
Also, I can smell smoke on anything. If you are a smoker, I would say, chances are, your bag smells like it as well. It just seems like there is too much in her favour and against yours. I would refund the money and move on. Good luck.
