How do I know if I have won the bid or a lot?

Log in to LOT-TISSIMO and go to "My Account" at the top right of the LOT-TISSIMO page. 

There, under "past" (Show all auctions), you will see a number under "Winning Bid" that indicates how many lots you have successfully won. If you click on this number, you will also see which lots you have won and at what price.

If you want to check winning bids older than 6 months, please go one step further than described above and click on "won lots" under "Older than 6 months" on the left.
