Easy Way To Maximize Rakuten New Member Bonus

Through December 25, 2020, Rakuten is offering the best refer-a-friend-bonus I ever recall seeing:

If you refer a friend to Rakuten and they spend $40, then both the person referring and the person being referred receive $40
In order to be eligible, the person being referred needs to make a purchase within 90 days

While I’ve written about this promotion before, in this post I wanted to highlight the easiest way to take advantage of it, as it’s an option that a lot of people overlook.
