Mystery solved. Apparently dh had let the rewards points on his credit card just build up for the last few years, so he randomly cashed them in the other day and paid off the credit card bill (where I had already scheduled a payment for) and dumped the rest of the money into our savings account.

Dh and I handle money very differently.

They send checks yearly with car insurance if they have a profitable year.

nope!

I had around $1800 show up in one of our credit card accounts and around $1300 show up in our checking account, labeled as “rewards”. Never saw anything like that before. I’m thinking it must be an error. I’ll call them later, but wondering if it’s some global glitch or something.
