Thanks to Kottke.org for the information.
It looks like Amazon has removed its cap for Associates, so that only computers are capped at $25 a purchase.
Previously, the most you could earn if a referral was $10, even if the item cost $3000 and the referral rate was 5%. Sometime in the last month and a half, someone used my associates code to purchase a printer for close to $600 and gave me $28 for “selling” that printer for them.
This is cool, you have to try it. I guessed 71244, and this game guessed it! See it here – http://www.funbrain.com/guess/
