Buy 2 products get cheaper for free

Free plugin just sorted items by cost , got 54,48,42,36.
and product filters selected 54+48(zero) and 42+36(zero)

You need this rule https://docs.algolplus.com/algol_pricing/bogo-discount-help/#b4
Look extra selectors in below product qty
at screenshot https://docs.algolplus.com/wp-content/uploads/bogo9-1.png

But it requires pro version.
We provide this version If you submit ticket to https://algolplus.freshdesk.com/

Thank you very much for the answer.

I tried it with the PRO version, but it still does not work 100% all right. The problem is that we have some product variations at discounted price (discount set up manually on the edit product page). It seams that the rule is only taking the base price to check which products are the cheapest, not the discounted price. Please see the screenshot here: https://drive.google.com/file/d/1tiQVNb74i0radgFz5ZLBe1GX4HMxyP3l/view?usp=sharing.

Is it please possible to make it to work correctly even if some products are already discounted?

Please, visit >Pricing Rules>Settings>Calculation and set “Discount sale price” in 1st dropdown.
