Still wondering these questions?
We always try to get the best possible price for your products, but we also want to keep prices reasonable so that as many products as possible sell during the sales period. Our pricing takes into account the brand, condition, age and demand of the product.
Prices for children's basic clothing are around €4-8, and for adults €7-20. The price of branded clothing and outdoor clothing varies according to demand and brand. The price and availability of similar new products also influence pricing.
In the last days of the sales period, we will reduce the prices of all products by 30-50 % to ensure sales. You can also submit price requests if you wish.
Many customers wonder whether there will be anything left over after the commission and handling fee. The answer is: YES! Over 99 % of our sellers end up in the black. Our sales percentage averages 70-80 %. We know what price level will move products. For the best returns, carefully read the instructions of your starting seller and only bring intact, clean and tidy items for sale!
Absolutely worth it! Most of our customers buy clean, everyday basic clothes. While there is demand for brand-name items, affordable basics sell best. Bring clothes purchased fairly recently—items over five years old have little demand, and those over ten years old have almost none. Ensure the clothes aren't too worn, stained, or damaged.
