This "Buy Used" challenge is helping me so much.
Here are some purchases I've passed up on so far this month, mostly out of laziness, because I wasn't motivated enough to track down a used version of it:
Teapot $40
Vermicomposter $90
The great thing about this challenge is that it allows me to continue saving money even when I'm ahead on my budget. For example, right now mint.com says I'm $240 ahead on my budget this month. (That means: if I were to spend $240 right now, the percent spent in my food/gas/fun category would match the percent of time passed so far this month.) If I weren't on this challenge, that $240 would be spent in a heartbeat on whatever urge happens to come up.
But even though I have $240 "available" for spending, I still don't plan to spend it right now. Why? Because spending it would involve effort. Research. Googling. Car trips to obscure places. I'd rather just relax with a nice cup of tea and enjoy my Sunday.
Buying Used - the best way for lazy people to save money! (I'm kidding of course ... by "lazy" I just mean people who value their time.)
