1. Some of these are no cheaper than the current brand new shop prices. Take a look on Brickset. Some of them look a bit cheaper. Some of them look more expensive! Why would Wu be €15? So it looks like average value.

2. It depends if you really want to collect Brickheadz for some reason. Personally I think they are only useful for the parts! (Although the parts are very useful for MOCS- Nice tiles and snot pieces...)
