Our 6"x9" promotional postcards are perfect for RV dealerships, RV parks, and product advocates. They can be provided to your customers, friends, or travelers you meet on the road. Cards have a 3"x1" area on the back to include your coupon code - when your coupon code is used your affiliate account will automatically have a commission applied. We also include a matching number of 3"x1" stickers with your customized coupon code that can be applied to this area (please note that stickers are not pre-applied). For retail location such as RV dealerships and RV parks consider adding a postcard display holder to your order. When placing the order, please provide your affiliate referral ID or coupon code in the 'order notes' section. You must be a registered and approved AirSkirts affiliate to receive this product. If you are not yet registered please visit our affiliate center to register prior to placing an order. We charge a small amount for promotional materials to partially cover our shipping costs (we cover the costs the material itself). Once you receive your first order we are happy to refund this charge in its entirety. In some cases we are able to waive this fee - please contact your account manager for more information.
