Swaps for free
Title Trader allows users to swap DVDs, books and CDs free of charge. Swappers are rated positve / negative by the other trading partner, so you can get an idea of whether the goods are likely to be shipped punctually and in good condition.
Title Trader provides the service world-wide and entering your items to be swapped is easy – you just enter the ISBN or UPC and the system adds a full description of the item. Users can review the items, similar to the review system in Amazon. There seem to be enough people offering to ship to Germany, and getting to our local library when it’s open is almost impossible if you work, so I might give this a try.
