Before this event I ordered from the previous events of getting these cards in total around 10 separate orders.
Out of the 10 cards I had four of them that would not work due to someone else I suppose randomly entering different letters / numbers from their cards and resulting in using mine.
I contacted support at BRS and they made it right by adding some points to my rewards and I was able to redeem them that way.
All 10 cards were $10 each.
IF you salty saline junkies have this issue with your card reach out to BRS support and explain to them with your code numbers and see, they likely will make it right and seems they are aware of some lug nuts out there stealing by one method or another.
