High Eng Audio Auctions on Ebay does not honor their deals


Purchased a pair of Eminent Technology LFT-VI speakers from them off Ebay and they delayed shipping for a week  saying that their staff had contracted COVID.
Yesterday they said that they cannot ship the speakers because the shipping was too low and asked for money to ship them to me. 
Very disappointed with the way they conduct their business.

I bought two items from them. Both transactions were "wonky". I bought a pair of Snell speakers. I picked them up. They were advertised as in excellent working condition. When I hooked them up something was off. I then noticed that all mid woofers were delaminated. The seller said they had no idea where to get replacement drivers. (odd them being in the business). They did offer a refund. I would have had to drive them back. I decided to keep them as I did get a steal of a deal. Highendaudioactions canceled the sale on EBay so I couldn't leave feedback. Second item was an Esoteric CD player. They advertised it as in perfect working order. It wasn't. I returned it. They balked at EBay that the problem was with me. The player went back on their site. It sold again. It turned up again for sale one month later For Sale As IS! My experience. Joe
I have sold hundreds of items on Ebay. Occasionally, I price the shipping too low. In every instance I eat the loss since it's my fault. What the seller did to you is not a good way to do business.
At least they could have told you how much the additional shipping would be so you could make a decision or negotiate (split the difference) not that you legally needed to.  Let’s say it was $200 more. For another $100 I’d probably say wtf. 
I have some experience with ebay auctions - not for audio equipment but for items of various values.  In every case the seller either quoted a flat rate for shipping to various locations or stated explicitly that shipping costs would depend on location and could be quoted privately.  In every case, the seller did in fact ship and charged the quoted rate - occasionally less. I have never had a seller behave as this one apparently did.  As Op describes it, this seller did not behave very honestly.
