There are several sites where you can get a small amount of bitcoins (more like fractions of bitcoins, really) for entering a captcha or clicking an ad. Find out more in
this topic.
It's by no means 'worth the pay' (i.e. it's quite not enough to make a living with it

) but just consider it a test to get yourself started with some bitcoin pennies. Some are stupid and require you to waste lots of time, some are plain and simple, just enter a captcha or click an ad or something, and you'll receive coins within a few hours.
very cool, thank you for the tip !
I keep hearing about being able to use "MoneyPak" refillable debit cards (liike the kind you can buy from a convenience store), and these can bve used to buy BTC. Is this true? How could I go about doing that? There is a store right near me which sells these GreenDot MoneyPak cards, I just need to know how to turn that into BTC.
