Short answer
In AffiliateBoxes, set up each store as an affiliate network (Amazon, Walmart, eBay and so on), then add an affiliate link for each store to the product. The product box shows one buy button per store, ordered by the priority you give each network, with its own colours and link settings if you want.
Why offer more than one store?
- Readers have favourite stores. Someone who never shops on Amazon may happily buy the same product at Walmart — through your link.
- Out-of-stock protection. If one store runs out, the other button still earns.
- Better commissions. Commission rates differ per store and category. Put the best-paying option first.
- Less dependence on one programme. Changes to a single affiliate programme hit you less when your boxes link to several.
Step by step: multiple buy buttons in one box
- Add your affiliate networks. Under Affiliate Networks, add each store you work with. Supported networks include Amazon, Walmart, eBay, Etsy, AliExpress, Awin, CJ, ShareASale, Impact, Rakuten, FlexOffers, ClickBank, PartnerStack, Booking.com, Tripadvisor and more — plus "Other" for anything else. The network's name is the default button text, such as "Buy on Amazon".
- Set the order. Give each network a priority (in its advanced options). Buttons are sorted lowest number first.
-
Set link options once per network: open in a new window, and
relattributes such assponsoredandnofollow. - Make a button stand out (optional). Buttons follow your box style, but each network can override its button style and colours.
- Add the links to the product. Import the product with the browser extension from one store, then add the affiliate link for each other store you want to show.
- Insert the box with the WordPress shortcode or block, or the script tag on any other website. Every box and comparison table using the product shows all its buttons.
Bonus: coupon codes per store
You can add coupon codes per affiliate network, with a description and an expiry date. A coupon button appears on the product box; readers click to reveal the code and copy it. Expired coupons disappear automatically.
Tips
- Two or three buttons is plenty. More choices can mean fewer clicks.
- Use clear labels like "Check price on Amazon" and "See it at Walmart", so readers know where they're going.
- Check the rules of each programme you join — some have requirements on how prices and links may be shown.
