Vital care rewards: Scam

I’m so fed up with their stupid exclusions. How am I not allowed to use my 20% on litter and do an in store pick up? You can’t even cancel the 10% for 50$ for pick up bs because “iT’s A pRoMoTiON”. Safe to say I will not be renewing this plan anymore. I can use that 20$ to actually just buy the litter. You used to be able to stack them which was nice but all of a sudden it keeps changing and defeats the whole purpose of this “rewards plan”.
