Chips prices

Why do you sell me chips with one price but later take +50% more of this price?

I dont know what the whole storry, but this is a community forum.
My guess
First Purchase Special!

really upset on this site, buy chips and then cards change and you lose them all because all changes, have full houses and someone higher everytime…I paid over $200 for fake chips, this is a rip off…
no way to build up chips on this site, unless you keep spending real money on fake chips…

well, it’s not fun indeed
