Create extra and unlimited product options (price per option)

OptToFly gives every product option a price of its own. Set a charge on each value of your existing Shopify options, like Color or Size, and the page shows the exact price for any combination, with zero extra variants. Build add-on sets: reusable custom option forms with swatches, buttons, dropdowns, checkboxes, radio buttons, text fields, and date pickers, so customers personalize gift wrap, engraving, and more. Link add-ons to products, charge flat fees on Shopify Plus, and track option orders
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows OptToFly: Product options on a store, it is there.
