Cutting back on material things is very hard. I'll check out your recommended site, Grinity. I have been taking steps to end my book-buying addiction. When DS4 was born, my addiction transferred to books for him, and this turned out to be fine, since we read them over and over and over. But now that he doesn't care to read the books over and over, I made the big switch to the library yesterday. I was so proud. For one day. Then I read about Penrose the Mathematical Cat on another post, and of course our library system doesn't have it! I slipped already.
