It’s communication policy is awful. They send out emails with no contact details to CUs asking to contact Catawiki in case CU disapproves or wants an alternative. It is impossible to contact anybody directly. Help section asks for info which is not available to CUs before accepting request. Its commissions are the same independently from price and are enormous, especially for items above €100. Both seller and buyers buy commission but there are professional sellers with sweetheart deals which dominate the products on offer. Its not a site for the common Joe. Valuations are horribly inflated so that reserve prices are horribly inflated so that commissions intake is maximised. The result is that it is very difficult to sell higher priced items, say around €900-€1200.
