You can create as many as the integer value within the database can handle. I think this is approximately 2,147,483,647.
Remember though that if you have hundreds, or even millions, your store needs to run through all of these to check that the discounts are valid, so try not to have 2 active ones, and thousands of disabled ones, as this will just slow your store's performance.

Good point about not having too many to slow things down but I am having trouble deleting coupons once they are not needed anymore.
When I delete, it asks me to confirm, I say yes. Then it just makes them inactive. This happens whether they were inactive in the first place or not. I thought it may not want me to delete coupons which were still within the time period but the expiry date does not seem to make any difference either.
I want to start using more coupons but dont want to create a whole bunch that I cant delete later.
Any suggestions?
cheers
