CubeCart

CubeCart is an absolutely legendary, deeply entrenched UK-based veteran titan that mathematically dominated the early 2000s "Turnkey Script" market. It engineered an incredible transition into a highly reliable, modern PHP application. It is the absolute weapon of choice for fiercely independent, old-school European retailers and veteran agencies who mathematically demand an incredibly stable, 100% open-source shopping cart they can physically host on their own dedicated metal servers.
