Postal
Arbitrage

As of 2025, a stamp for a letter costs $0.78 in the United States.
Amazon Prime sells items for less than that... with free shipping!
Why send a postcard when you can send actual stuff?

I found all items under $0.78 with free Prime shipping -- screws,
cans, pasta, whatever. Add a free gift note. It arrives in 1 or 2
days. Done.

You're not only saving money. It's about sending something real. Your
friend gets a random can of tomato sauce with your birthday note
attached. They laugh. They remember you. They might even use it!

In 2023, I ordered $1 cans of beans to a bunch of extended family
members. It ignited our family group chat for a few weeks and
everyone was super into it. Pictures of beans started rolling in.
Then they started sending random stuff to each other. An asbestos
warning label, cookies, a tin of sardines. Someone even sent a
pregnancy test to my grandmother.
