" call me for the approval of the offer in case someone got interested on my items" "two years"
??? I have never heared of such auctions.
For me Auctions are TIME LIMITED only extended A LITLE if geting a NEW offer close to the end of the time limit.
/Most auctions are started and ended within MINUTES for each item, and then they start and end next.
/Internet auctions (as for instance Ebay) have several auctions running at the same time, but are ended within a few DAYS (perhaps weeks).
And after the auction has ended, the money are send within ONE MONTH or so.
Most auctions have NO MINIMUM PRICE if seller don't have put one. (Except most auctions have a VERY LOW GENERAL minimum price.)
If I understand corect you have put minimum price only at ONE item =10k. Your other items have NO MINIMUM price, so they can have been sold very cheap. If so it's possible your items have been sold for a litle more than 10k.
(It's common to make bargains at auctions, but some pay to much too by they can't examine things proper at auctions - and some pay to much in "biding fights" because they find it a "lose face" situation, if they don't winn the biding
When two persons think "lose face" in a bidding war, then such offers can become MUCH higher than what the item is worth.
(Myself I don't bother to be in "bidding wars", so I have made many bargains in auctions, but also paid to much in a few cases, when the items were broken.)
Auction houses are normaly suppoused to have lists where it can be seen what each item is sold for, and who is the seller, so sellers can check afterwards, if not believing the auction house...
