I'm trying to grasp the difference in how "coupons" and "discounts" are used.
It seems that "coupons" can be applied as either a percentage or as a specific dollar amount - but only to an entire sale and not to an individual item.
And "discounts" can be applied as only a percentage and NOT a specific dollar amount - but to EITHER an entire sale OR to an individual item.
Other than that, is there some other basic difference in how the two work? I like the flexibility it provides, I just need to get the terminology straight!
