Maximize AOV with Fether, robust all-in-one app for Frequently Bought Together, Product Bundles builder, and Product Add-ons. Our AI analyzes order history to generate smart upsell bundles automatically. Easily create classic Buy Together deals, show high converting Customers Also Bought sections, or display AI powered Related Products storewide. From simple cross sells to complex Amazon-like themes, Fether empowers you to quickly grow revenue with our smart and custom product bundles app.

Shopify caps you at 2,048 variants per product. Globo removes the cap. Build option sets from 30+ field types - text, file upload, colour and image swatches, dropdowns, dates and dimensions - and apply them to one product or the whole catalogue. Charge extra for options that cost more: add-on pricing runs on Shopify Functions, so discount codes and taxes stay accurate. Conditional logic hides options until they are relevant, and every choice flows into orders, packing slips and POS.

Stop settling for basic, one-size-fits-all promotions. Launch advanced upsell and cross-sell campaigns on product and cart pages in just minutes. Use product add-ons / one-click add-ons to recommend related items with BOGO or Buy X Get Y offers (including automated discounts or combined discounts). You can also set up Frequently Bought Together with Amazon layout to sell in combos/package to boost AOV efficiently. Increase conversion rate with promotion badges or free gift with product offers.

Dynamically display order preparation and delivery dates on product pages. Enable merchants to customize date formats, languages, and visual styles (font/color/icon size), while setting distinct delivery rules for specific products, collections, countries, or vendors. Streamlines customer expectations with transparent timeline management.
