If it was an option, like you can currently choose to buy Amazon gift cards or enroll in Prime, sure. Even an option with incentives. But if you move towards making proprietary currency the only way to pay in a given area, it seems shady to me. Not illegal-type shady, but has-bad-motives-type shady. These kinds of proprietary currencies are a typically deliberate attempt to reduce the transparency of prices, by adding an addition layer of indirection people have to mentally jump through in order to think accurately about and compare them (you can see that in part in how most such currencies pick weird exchange rates, not decimal ones that would be easier to think about).

- beowulfey 14y agoOne such example could be the Microsoft Points - perfectly falls under your description. I can never remember the exchange rates, and they deliberately offset the prices so you always have residual points. For example, the minimum points you can buy are 400 ($5) but the cheapest item is 80, then 240, then 360... so you will never be able to spend ALL of them entirely (barring many, many transactions).
- jacques_chester 14y agoAn additional twist is to price things in prime numbers so that buying multiples leaves a residual balance.
- eterm 14y agoBut isn't every number the sum of two primes?
- jacques_chester 14y ago> buying multiples Plus there's stuff like using off-by-one values for fractional exchange. Eg 79 points for 99c, or vice versa. If you step to 80p / dollar it's easy to calculate a sufficiently-good approximation mentally, but lots of people aren't used to mental shortcuts like that.
