Do the products in my store update automatically?

Yes, your products and all the offers will update automatically. This includes the product price, images, description, stock status, etc.

Any offer you add to your store will stay updated with the latest information directly from the merchant (Amazon, eBay, Etsy etc.).

In your store admin area, you can force an offer to update, but this is unnecessary as your store will do this in the background every 2 or 3 hours.
