Selly is especially built for Shopifiers to increase sales in many ways:

Smart Discount

  • You can display your discount offers to your customers with many types such as free gift, free shipping, BOGO, buy X get Y.
  • Selly uses the latest Shopify API to have the best discount function. It means NO duplicating variant, NO generating ton of discount codes, almost NO changing your theme.
  • Discount automation of Selly and discount codes of other apps can be applied together.

Up-sell popups at Aha moment

  • These up-selling products are automatically selected by AI based on your sales history or manually selected by you for a specific marketing campaign.

Cross-sell sections

  • Selly displays recommended products at the bottom of pages. Fortunately, Selly has no design for this feature, because these sections will be displayed exactly following your theme design.

  • When customers reach the goal, the offer will be applied automatically.

I don't think there are any apps out there that pack as much Value in what they offer than Selly. Not only Value, but Quality as well. The App does what it does quite light and fast. Installation, a breeze, and the learning curve is super easy. The way it integrates with my shop is very transparent, the discounts are so logical and just work as you would think they do. My pages still load fast. Wrap this up with Stellar Support that answers within a few hours and are excited to try diffrent ideas for future updates. This is an easy 5 star App that will sure grow to be a top contender in the shopify App store
