LemonPick Product Options

Sell paid add-ons like engraving or gift wrap, and run test carts that check your checkout totals.

Options shoppers understand. Dropdowns, swatches, checkboxes, text fields, file uploads and conditional logic on any product, with a live total on the product page.
Prices set by Shopify, not theme scripts. A Shopify Function recalculates add-on prices at cart and checkout, and invalid or missing choices are blocked.
Checkout Guard. Test carts confirm every add-on is charged correctly, on demand or on a schedule, and every option change is saved in version history.

Install LemonPick from the Shopify App Store, then open it from Apps in your Shopify admin.
