Hi,
I like the cobi sets a lot and got frustrated that, unlike for lego, there seems to be no price tracker website for cobi sets. As a COBI collector I got tired of two things. Not knowing if a "deal" was actually a low or just a marked up RRP, and not knowing which sets were about to go out of production until they were already gone and selling for silly money.
So the only logical step is too stop my own excel voodoo and build a website that does exactly that. Currently it tracks two countries: Netherlands and Germany but will add other countries later.
