In the affiliate log in area, I read the FAQ and under the Tracking and Payments section:
What is the cookie time? Cookie time is the maximum amount of time between the last click and the conversion that you will still be credited for the conversion. We have a cookie time of 30 days This means that if you refer a customer today and they purchase our products within the next month, then you'll be credited for the sale..
If the last cookie in the door within 30days gets credit and sale as I interpret it, then there is a need to update this in on the AliDropship affiliate FAQ section stating this. Will remove any guessing or assuming.
