Gems: reasonable start but never finished

Im new to these forums, but i play clans constantly. And as everyone knows its ethier gems or wait a long time to do anything. Now when i first even looked at the option to by gems i was expecting to see outrageouse prices for small returns. But supercell did it justice and offer a reasonable amont of gems for a stab instead of a gunshot to your wallet. But what made me upset was they didnt put a 99 cent option. I have no problem tipping a good game. But i dont like when the waitier looks at my tip and looks at me like i owe him more. Im just sayin. Ps: i know i crazy for buying gems! But agian i dont mind it if its a damn good game!
