TopCashBack $10 off $10 Offer

I don't know if this is randomly targeted or how exactly it works, but I got an "Exclusive Offer" from TCB, yet a family member didn't. We aren't sure if it's because they just had $5 off $10 Bonus a week or so ago.

Anyway, if anyone wants to look for an email with the subject: $10 Bonus - Exclusive Offer!

It says $10 back as long as you spend $10 or more at any merchant that has TopCashBack.
