I'm trying to add a PayPal button to my site. What HTML code do I need to add to offer a 10% discount on the total only if 3 or more items are purchased?
So, if the item is €100, 2 items would cost €200, 3 would cost €270, 4 would cost €360 etc.
I can see discount_rate and discount_rate2, and can make it discount on every item, but don't understand how I can achieve the discount I explained above.
Could somebody help me out on this? This is the link to the various codes: https://cms.paypal.com/us/cgi-bin/?c..._htmlvariables
