How much does your tailor charge?

i went and got my suit tailored today, i need the suit to be tighter around the stomach cause i lost a bit of weight, i also needed the length of the sleeves to be a bit longer and the pants were way to big so i needed them fitted. altogether it cost me $150, is this too much cause i feel like a got ripped off, i could just but another suit for $300 on sale.
