Any advice on making your own wine?

When I buy wine, it's usually $10-$13 a bottle which doesn't seem like a lot but adds up. I'm not too picky about wine and have bought some brands of boxed wine to get more bang for my buck (also sometimes I don't want the whole bottle but I don't want it to go bad).

Does anyone have any advice on making your own wine? I googled a few recipes so I could also start there.

Thanks!
