Never presume the seller is going to discount s/h to what you think IT should be,
Always ASK FIRST,
before making multiple bids/purchases.
IT would seem if the seller said in description that they would combine and ship at a discount rate, they will as soon as you pay. According even to you he did invoice you at what you think is a discounted rate.
(he;s only giving about $15 off) So far I have e-mailed the seller 5 days in a row...He has not responded.
I suspect that is not all that was asked. Thus the 1 possible reason for no reply from seller.
Will Ebay doink me with a non paying bidder over this? IT is entirely possible, IF the seller pushes the NON-payment issue.
Do they expect me to pay no matter what kind of outrageous charges he tries to drop on me? No. IF the seller was charging you the same or more than stated as a combined rate, that might be outrageous. You said IT was invoiced $15 cheaper. How is that outrageous?
I say he is screwing Ebay out of revenue IT would be YOU skewing ebay/paypal out of any fees.
