Canadian Postal Arbitrage

postal arbitrage (noun): using Amazon's hyperefficient logistics network to send random gifts with messages attached for less than the cost of a stamp.

As of 2026, a stamp in Canada costs $1.44. Amazon Prime sells real, physical items for less than that... with free shipping! Why send a postcard when you can send actual stuff?

I found all items under $1.44 with free Prime shipping: crackers, screw bits, piano strings, whatever. Add a free gift note. Your friends get a random gift with your words attached in 1 or 2 days.

Not only are you saving money, but your friend gets a random can of tomato sauce out of it, with your gift note attached. They laugh. They remember you. They might even use it!

Inspired by the original Postal Arbitrage made by Riley Walz.
