Need app for adding purchase options
I am considering building my site on InMotion, and am wondering if you have an app available that lets a customer add options to a purchase. For example, if I offer a basic porch swing for sale, they can go down the list and add options they want; ie. names burned in to the swing, cup holders built in to the arms, heavy-duty chains, upgrade the choice of wood, etc. As each option is selected, the appropriate amount is added to the price. Is there such an app available on this site?
