Beware! Catawiki creates fake bids on your behalf, so you "win" the auction without submitting the bid and then you must pay for it even if you did not outbid! There is no email for the new (out)bid but they send you "YOU WON!" message as if you submitted a bid which you never did submit in the first place! I have made enough research and they've already scammed me once with a similar situation like this and they did not present a proof, but I gave in and paid for it, even if I did not have to. They don't have an email sent to me of my new bid, which I clearly did not bid or outbid, but the demand I pay for something I did not outbid in the first place! Over many months I made research and I can tell many failures and shady stuff going on with Catawiki and some of their "experts" are real idiots. Documented proof is available.
