We are currently transitioning some code to new APIs of certain product data providers we use. As a consequence our price comparison listings are not showing product prices from the usual range of retailers, but only from eBay and Amazon.
We intend to remedy this as soon as possible as it is important for us that we display the broadest possible range of prices and help users find the lowest price online. So we will hopefully have this fixed by the end of this week – apologies for this.
