Since UltraDev Cart II uses Session and Cookies isn there a limit on how much you can store?
Yes, this limit is imposed by the server and or browser that is being used and this limit is around 4K. So if you need to have individual ordering 50 items or more at one time in one order you might reach this limit. This number is just an estimate, depending on the type of hardware your site is running on and the stuff you are selling it’s possible this number could be higher or lower.
