In preparation for the release of Spender AutoCoupon and Chooser AutoCoupon, I’ve written more about using coupons in Zen Cart with Big Spender, Big Chooser and the AutoCoupon mechanisms.
A number of people wanted coupon dependencies for tracking without the additional discount of a coupon. I had been suggesting the use of a $0.01 coupon, but yesterday I verified that a $0.001 coupon will work correctly, showing no additional discount, but still getting tracked in the redemption table (which a $0.00 coupon would not).
