It is such a handy site. I've had some from there that I loved and some that were not in great shape, but I've been able to use them still.
I can't remember if I've mentioned it in this particular thread, but my other favourite money saver has been using cloth wipes. It sounded like more work, so I didn't try them right off, but I've actually found them to be less work than disposables. If I'm using the disposable wipes I have to separate them out from my flushable liners and the wash and figure out what I'm doing with them--not super bad when it's just wet, but kinda nasty when they are poopy. I find it much easier to just use the cloth wipes then throw them in together with the nappy to be washed.
If you look at what you'll save using those, you'll find they often cover the cost of your whole nappy system. You can buy them yourself, but I had a few I liked that a friend made. Once I saw I liked them, I just went to a fabric store and bought some flannel and other soft fabrics which I sewed together. It was super-easy, and I used some of the fabric to make a bunch of cheap face/hand wipes for the kitchen after meals as well.
