Challenge Newbie budget question:
Say I buy parts for my challenge car at the auto parts store (in this case a battery and alternator) and I get $15 in rewards bucks from the auto parts store to use on a future purchase. If I use the rewards bucks to buy $15 in part(s) for the car, do I have to claim this at $15 against my budget or is it "free" because the discount was earned buying other challenge car parts? I don't know what I'm going to use the rewards bucks for yet, just trying to weigh the options. Thanks!
