Coupons/discount codes you can create yourself

How about a feature where every ZAP customer can create their own coupons? Currently, the username is always included in the coupon, e.g., UserName-a-1234.

It would be nice if it were possible to create individual coupons for each person.

It would also be good if using the coupon were sufficient to receive a commission. This would mean that an affiliate link would no longer be absolutely necessary (and therefore no cookie would need to be set in order for the advertiser to be remunerated).
