After clicking on the appropriate link, you will be asked to sign into your Amazon account. Amazon keeps track of how you got to their website so they can give appropriate credit. Once you are in your account, you have access to your saved items, profile, and even Prime shipping service.
Both Amazon and third-party items count toward your total shipped items, which determines your referral rate. As you move from one level to the next, the referral rate in the new, higher level will be applied to all items shipped during the month. For example, if you refer 100 shipped items in a given month, you will be in the third level and earn 6.50% on all general products and flat fees on other product categories (e.g., 4.00% on CE Products), whether shipped or sold by Amazon or a third party, shipped during that month (subject to any caps set forth in the Operating Agreement).
Here is a chart detailing the referral rates in the Performance structure:
Caps: Personal computers (both desktops and laptops) have referral fees capped at $25, and Amazon Video On Demand as well as Amazonmp3 products are capped at $1.50 per item.
Additional exclusions may apply. See the Operating Agreement for details.
