People pay more for worse things, so I can see you'll get money out of this.

Envelopes, checks, postage, gas / your time trip to the post office - agreed isn’t a lot of money probably about $3 + your time.

Less. Gas is not a factor. Envelopes are at the grocery store, which I'm going to go to any way. Postage is sold at Costco, so that's not really extra. And the mailbox is right where I live. The time to get to the mailbox doesn't count as, well, I do need to check my mail anyway. So really, the only time spent is:

1. Finding the items at the stores I already shop at.

2. Write the check.

3. Apply the stamp.
