first of all, you will only get your bonus on 8 and 9, no bonus on 10 unless we get into the next 10 rounds then you will get 1 peccent of every level that sells out. I think thats right.... so, if you were to buy in level 1 and they sell out all 20 levels, your bonus would be 19 percent. level 9 you get 1 percent and 8 you get 2 percent. they wont give out the bonuses until everything is completed, i believe.
