Honey, if I took all the money distributed throughout all the envelopes at the beginning of our fiscal month, it would barely pay for that thing!
I sometimes do a little juggling with the money in the envelopes, moving extra funds from "clothing" and putting them in the miscellaneous slot. You aren't supposed to do that, but hey... I never said I was perfect.
We have an emergency fund that we absolutely won't touch for non-essentials. So the money isn't coming from that. Of course we aren't doing credit any more, except for gasoline, which is paid in full every month. So I'm not getting it on payments. I have a household account that sometimes has a little extra in it, but never that much.
Cliff actually offered a portion of his tractor fund to me. It's one pile of money I never touch, and he normally doesn't offer. I didn't ask, but I accepted when he offered.
