For me catawiki is a mixed bag of surprises. The vast choice is tempting but descriptions and translations are laughable. The listings are riddled with mistakes and often are confusing and missing important information. Experts? Forget it. That is just marketing. Some sellers are just dumping junk, well presented. Although packaging by some sellers is excellent, other just dump items in a box and hope for the best. Shipping cost are occasionally vastly inflated. Recently catawiki's meamingful reaction to complaints has deteriorated compared with last year. Expect "unmonitored mailbox" replies when seeking help. Some sellers essentially refuse to send auctioned items. In short using catawiki is time consuming in frustrating
