So we have been using the coupon code at 50% off and another at 40% off to sell to qualified customers at discount pricing. But we would like to give retail customer the incentive of free shipping and somehow exclude people with this these coupons from this additional discount. Any suggestions?
Also we have a couple items that are very expensive to ship and I wondered it there is a way to exclude these items from free shipping. I guess a handling charge could be one option.
