1. You can add to products but this has no big sense. Posts are faster and
have more functions for coupons like expiration. Products have another

2. This is depending on your links and affiliate network. Its not depending
on site.

1.Can you please explain why coupons need add in the “ post “ why we can’t post under “ product” section?

2. As most of links are affiliated link, how to enable 90 days cookies policy( so if user click on the product.. it validate 90days)

this is correct https://prnt.sc/uoz6nr

Currently, you have no any coupons on site. Add them

What did I do?

http://prntscr.com/uoz5f3 I had added the code(rehub_offer_product_coupon – coupon code) under product but in the filter panel,

https://prnt.sc/uoz5f3 - this doesn't nothing. Will show text
rehub_offer_product_coupon on product page, nothing else. Currently, it's
not clear what you do
