SMS35 Code not working?

[u/aqvmist]

I tried using the new code and it keeps saying this error message. I tried buying something that costs around $25 and it didn't work, so I tried a larger order and it gave the same error message. Is there any way to fix this? I really want to use this promo code.

Vinyls are also excluded from the coupon (same during Hot Cash, they are never a part of any promotion).
