You don't explicitly need to buy doges (although you can and a lot of people are doing that), you can simply run a miner program overnight, in such case all you pay for are electricity costs.
I found out about dogecoin quite early on and initially managed to scoop up as much as 8000 doges over the course of several hours every day with my modest laptop (Intel i3 2370M + GeForce GT 630M). Yet, the mining difficulty has spiked up since then, now I'm hardly getting more 1000 doges when I leave the machine running overnight. I'll probably just reach 50k and give it a little break, hoping that the currency will recover from the abrupt fall in price (down from about $1.40 per 1000 doges to $0.80 per 1000 doges) which happened yesterday
