So call this number 877.277.5977. Politely talk to them and ask for another chance. Usually they are ok for this. The lady I talked to knows Fatwallet, Slickdeals, Sder and e-junkies.
Anyway, I plan to be more cautions using coupon at staples. Shopping at store only is too much hassle for me.
No, they don't reset the list every year.
The blacklist is also known as "Access Restrict List", i.e. they will allow you shop at store only. No online access.
I heard someones even restricted from shopping at store. Not sur how they can tell ...
