SwatchBoost adds a popup to your product pages that lets a shopper pick more than one colour of the same product in a single step. When a customer clicks Add to Cart, the popup opens and each colour they choose is added as its own line item. You set discount tiers, and matching discounts apply automatically at checkout. The popup supports right-to-left layouts and Arabic. You can choose a preset theme, set the accent colour, edit the popup text, and choose which products show it.
