Could not create Pay to Feature or Pay to List with Featured Option

Ah, so in reality there are only two options: Pay to list and pay to feature. These can be used individually if you create either one. Or you can use both at the same time (where feature is an additional option). To do that, you choose 'Pay to List with Feature'. Since you already have a listings product it won't let you add that - so you'll need to delete the existing product, then re add.

Hey Paul, what are you trying to exactly? Do you want paid listings with the option to feature? If so, you only need the bottom option and that'll enable both.
