Copy/Paste and Clone Products
To copy/paste CubeCart products, you have to select one or multiple products, copy selected products and go to the category you need to paste items. When you're pasting products, you're creating the new items with the new ID numbers (duplicates) with product ID in the model name.
Clone Products option is actually like a combination of copy and paste buttons. It will copy selected product and place it in the same category with the new ID number and the postfix " - clone" at the product's name. This way is easier and faster than copy/paste.
