Ok, I admit I don't sell much on eBay, but I am just shaking my head over what this buyer just did to me. I listed a gold bracelet and put the postage calculator on the listing and indicated it would ship priority mail insured as per the ad. I send the invoice and then get payment, but the payment was reduced by $4.00 as a "seller discount." I e-mailed the buyer, and she replied that she recalculated my invoice because my charges were wrong (she somehow came up with different figures for insurance and postage) and then she sent payment. I already shipped the item earlier today and the $4.00 is not a big deal, but just have to wonder about this person. Why bid if you disagree with the shipping rate on the postage calculator? Who changes an invoice without even contacting the seller? This is not a big deal and sorry to vent, but I just don't get people. I would never dream of giving myself a discount without first contacting the seller. She is probably going to be a pain once she gets the item, but she had already paid so I couldn't refuse to sell to her.
