in my Shopify store I normally allow for the standard payment methods like PayPal or credit card for all products which works fine.
Now I want to add an offer for just one specific product A for the payment via invoice after 60 days (-> "try the product for 60 days for free and only pay the invoice if you're happy with it"). Obviously this payment offer should only be applied for this specific product A and NOT all the other products (-> pay first, then receive the product).
Is there any way to either block all other products from this payment method or allow this payment method just for product A? Or realize this scenario in any other way? I don't have Shopify Plus.
