I used to buy my bitcoins each fortnight on payday but the fees add up over a year of doing it that way so i now op to get paid about half my wage directly in btc, no more fees 
That is a good move for you, buying is too expensive while if you can earn it the better, we should focus on our way to earn bitcoins rather than buying if we don't really need that much. We only buy more bitcoins if we will use it as our capital in doing day trading and investing a huge amount of money.
