Oyvi review for Kaching Post Purchase Upsell

kaching post purchase is so underated imo, I never used anything else than Kaching and I heard that the other famous app for upsell is scammy in terms of paying per order : you end up paying the other app more than you make with them what I like with Kaching Post purchase is that you can have a 1K bonus machine up in like 30mins, I made 10-20k only in post purchase which is free money, it's a requirment on all stores PS : thanks Seb
