Wish Lists are a way you can let fellow traders know what coupons & actuals you are looking for.
Have Lists are where you can keep an ongoing inventory of coupons and actuals you have available for trade.
In the coupon database you are also able to create a Keep List. This is where you can keep your own personal inventory of coupons that you have for your own use.

These are intended as long term lists that you update as coupons, sales, needs and haves change.

You can now create your havelist and wishlist directly from the coupon database. See instructions HERE.

Use the search feature to find the coupons you want to add and using the action menu, select the list you want to add it to. You can add a note, choose the priority for the item on your wishlist, and enter the quantity.

Do I have to create a Wish List or Have List to trade?

Creating a Wish List or a Have List is optional. You do not have to create both. Many members create a wish list only or a have list only.
