Since not many NRA members use those discounts in the first place.
How many Discounts will each individual business lose?  10? 15? per year?

Only 13 passengers ever bought tickets using an NRA discount at Delta. And what did it cost Delta?
 
The Georgia legislature removed a $40 million jet-fuel tax break to punish Delta for caving to gun control advocates, airline spokesman Trebor Banstetter admitted that only 13 passengers ever bought tickets using an NRA discount.
 
That means each discount cost Delta roughly $3 million in tax breaks.
