I won't mention their "names," but I previously collaborated with other, equally well-known platforms. Everything was lacking there in almost every aspect that is critically important for the normal operation of a store. I even started to doubt the modern IT services market until I began testing Insales. Many questions and problems disappeared once I connected to this system. The store on Insales started to be indexed almost immediately, so the promotion issues resolved themselves as well. I want to thank the developers for this engine - it turns out that not many people know how to create such masterpieces.
