Coupon Codes questions

[jimbo17]

Can coupons be used to either subtract or add costs to a product because of of an extra offered by simply changing the - sign to a + sign?

Is there any limit on how many Coupon Codes you can create?

Thanks for your help. Jim

Thanks for your quick reply.

Just want to make sure I am understand you correctly that Coupon Codes can be used to either - or by using + add in an extra charge for a product?

Hello.
Coupons designed as discount (fixed or percentage).

Start by picking a random number between 0 and 31. (A-Z, 0-9, and take away 1, 0, I, O). Append that character to a string. so, g then h then j etc. You'll have ghj5jkg4 using the above example. Check that string for inappropriate language. You don't want to randomly generate something like 1fuck3r5. As suggested in the comments, removing just vowels may be sufficent, especially if you don't use numbers.
