What this check is
The cheapest additional revenue on the store is the item the shopper already intends to buy alongside this one. A bundle block on the product page makes that obvious instead of leaving it to chance.
How to implement it
Choose two or three products that are genuinely complementary, render them as a bundle block with a combined price and a single add-to-cart, and set the pairing per product rather than globally. Use the real discount you can absorb as the incentive.
How to verify it
Add the bundle from the product page and confirm both items arrive in the cart with the combined price applied and no separate discount code required.
