I flip through the magazines at the newsstand, and buy them if they look interesting. I used to subscribe to a bunch of magazines, but now I am down to two. I hate having to read through 50 pages of ads for 2 or 3 articles, especially after paying for the magazine. The schools usually have magazine subscription fundraisers, so I subscribe through them and rotate from time to time.
I did buy the big back issue set of SSWC from the fox chapel website, because it was such a great deal.
I also pick up a handful of used books on half.com when my paypal account starts to fill up.
There are so many plans you can buy directly from the authors, and the prices are pretty reasonable, and you're getting just what you want!
Our library has a surpising amount of books on woodworking, I don't know who donated them all, but they are a great resource as well. I probably should send a couple of ones I no longer need that way.... but I hate getting rid of books!
