I am a seller on catawiki. The first two sellings of mine were sold out undervalued, well, I sent it anyway cause I didn't know I could put a value on my painting. I tried again with two small paintings ( 20 cm x 20 cm ), I put 80€ for its value and another medium size ( 46 cm x 38 cm ) painting for 150€. Their expert Lisa KOK refused me and said " "From our experience and based on our knowledge of the market, we do not think that lot will attract enough interest from our potential buyers, so we can not include it in our sales." We apologize for the disappointment Please do not hesitate to submit other lots that we will examine with pleasure. " I got the two the same copy-paste answered for two different lots that I believe she copypaste from and to another lots as well. This is not what i expect how their expert to communicate with the seller. Below is one of the lots she refused. I think it's not a good place to sell art.
