"The CeX Concept - Buy Sell Exchange
Our business model is based on buying and selling from the same source, our customers. To succeed in such a business and overcome stock shortages or stock surpluses, we aim to achieve two optimal positions on all our products:
An optimal selling price which is competitive by comparison to buying the same product new. A price at which the product will sell.
An optimal purchase price, which the consumers are willing to supply the product.
We constantly look at product demand and supply curves and change our prices using the experience and sophisticated tools we have developed over the last 15 years."
