Questions about Discount Vouchers
Aravot asks;
Looking for a discount / coupon contribution found your site, was wondering if your contribution creates and sends coupon to customer upon registration and when customer uses the coupon, it deletes it from db. If your contribution doesn't do the above do you know any that does.
Aravot, my version of this does not send a coupon to a customer upon registration. It also does not delete from the DB after use.
However, coupons can be set up to be used only once per customer…so all you need to do is set up a permanent coupon of whatever % discount (on a use once basis), then send this coupon code to each new customer in their "welcome" email - or print the code (maybe print it funky using an image of a voucher) on the "create_account_success" page.
So, in a roundabout way, what you want can be done easily enough.
I do not recommend any of the other coupon contributions as they are all over-cooked and/or outdated codebase.
