First off, put your pitchforks down. It’s been 6 months. It’s NOT coming back.
Anyway, back in late December 2018, Spafinder had a promo code where you could buy their gift cards at 30% off. To a normal person, this is about as enticing as a Nutrisystem gift card. However, it was discovered that a Spafinder gift card could be used at a very popular online bookstore… And if you also did buyer’s club, you’re almost cashing it out at 100%, thus making 30% for every Spafinder gift card.
To make it even better, if that wasn’t good enough, you could use that Spafinder GC to buy another Spafinder gift card at 30% off, essentially an endless loop. So let’s say you started out buying a $500 Spafinder GC, you spent only $350 due to the discount. That’s your outlay. You then could buy another $500 spafinder gift card using that first $500 spafinder gift card and now you have a $500 spafinder gift card + $150 left over on spafinder gift card #1. Rinse and repeat. Your “profit” would essentially be $150 for each order.
I believe this lasted about 3-4 days before the bookstore stopped taking the GCs. By that time, most of the damage had been done.
