yep no problems here, even printed the coupon in black and white. just they can never seem to scan the coupon since it prints so big, but they just manually enter it anyhow.
However from working at blockbuster in the past, I know that it only matters per account, and per blockbuster. So if you have multiple blockbusters near you, they are NOT connected. If you have late fees at one blockbuster, then they don't carry over on the same card, also any coupons can be used there the same, also if you open an account at a separate blockbuster, they are two separate accounts due to separate stores. Blockbuster is not as smart as you think they are about that stuff.
