Coupons can be created for use during the checkout process. Simply create a Code that will be given to the buyer. The coupon can be for free shipping or flat rate, or for a discount off the purchase price – either as a dollar amount or as a percentage. A minimum order value can be set along with a start and expiry date. Set who the coupon is valid for – members only, or all buyers. Specify which products the coupon discount applies to, if applicable.
Single use only – coupon can be only used once EVER and it expires.
One time per email address – Coupon can be used once per email address
Override member discount – coupon is instead of member discount.
Override nonmember discount – coupon is instead of volume/case discount.
Override sale discounted price – coupon is instead of sale price as marked on the wine product page.
Always test your coupon and make sure it does what you want before you give out the coupon code.
