Discount coins get liquid

NEW YORK — Citigroup will be the first major issuer to use Mastercard technology to give U.S. credit card holders the ability to instantly redeem points on eligible purchases online and through a mobile app.The goal is to better serve digitally savvy customers with a rewards redemption process that operates at the time of purchase. Consumers opt in to receiving push alerts for rewards that can be redeemed above a certain dollar amount, with the rewards applied as a statement credit within three business days after the transaction is completed.

Purchase points, what I call discount coins. They should move around just like any other coin, but they require dual pricing.  Dual pricing is something I should be working on, I haven't given it much thought.
