What is “Avg. Trading-Price”?
We collect a lot of data from several databases. We also look into the past by getting real trading prices of a set of the last 6 month. We do this by requesting bricklink – one of the biggest marketplaces for brick toys.
Amazon prices are very high because sellers need to pay Amazon a lot of money for storage and kickbacks. So if you want to know the real value of a set, you should trust in the “average trading-price”.
