I did that for a while too, but realized the mental overhead wasn't really worth it - occasionally I'd get the super generic coupons of "Spend $20, get $2 back" and those were worth it, but most of the time I was adding coupons I'd never use.
The mental effort of going to the site at all was what I was trying to circumvent - now I don't even need to think about it (the clearer abstraction is that going from "2 to 1" is a much less drastic jump than going from "1 to 0" - completely removing the overhead is what makes this worthwhile, IMO, not the actual speed of the actions)
