I don't recomend this at all. Even if you pay a buyer protection, you are not protected. They give you 3 days to see if there are any problems.
I personally have ordered wine from different providers. I found out sometimes 3-6 btl like vinegar, for which i lost at least 100 euro per order.
No response, people don't care, no responsability.
Their answer was that i have 3 days to test the merchendise.
So if you order 100 btl you have 3 days to open them all to see if they are bad or not!
Terrible, will never use or recomand this to anyone.
Better prices on Amazon + they take responsability!
Don't use catawiki!
