Flying Pie Me review for Checkout Rules & Discounts

Oct. 31, 2025

I’ve tested a lot of checkout validation apps on Shopify looking for a way to properly validate delivery details, and almost all of them had some problem. Either they were too limited, missing features, or didn’t work properly when you tried to use more than one rule per field. Then I came across this app, and it just works. The only thing missing for me was a combined max character limit for the address fields. I asked their live chat if that was possible, and within 30 minutes they had added it. The team is very helpful, and the price is fair. Even if it only prevents one bad order a month, it already saves more time than it costs. I would definitely recommend it.
