Good news: i have changed the BO on all chips from 2200% to 2000% . So if you want one just buy one right away! .
Also i will remind anyone who might do not know this:
since some time chiping in or out does not cost 2.00 ped anymore but only 0.01 ped (thats right 1 pec!). So if you consider something like: "meh i would buy all those skills but the cost of chipping in will be too high" - well it won't!
Now it is better to chip out in smaller chips because you can satisfy clients who want big and small amounts of chips.
