Product prices and availability may vary from time to time. Because prices for and availability of Products that you have listed on your Site may change, your Site may only show prices and availability if: (a) we serve the link in which that price and availability data are displayed, or (b) you obtain Product pricing and availability data via PA API and you comply with the requirements regarding use of PA API in the License.
Upon your request but subject to our approval, we may issue you additional “sub-tag” Associate IDs that permit you to monitor and optimize the performance of your Special Links by including different sub-tags in the URLs of different Special Links. Under no circumstances may you associate any sub-tag with a specific end user of your Site (e.g., you may not dynamically assign sub-tags to users as they arrive on your Site for purposes of monitoring such users’ behavior).
Emails triggered by milestones, like anniversaries and birthdays, are fun to get -- who doesn't like to celebrate a special occasion? The beauty of anniversary emails, in particular, is that they don't require subscribers to input any extra data, and they can work for a variety of senders. Plus, the timeframe can be modified based on the business model.
