I want to offer my clients a discount if they buy 3 or more of a single product.

I saw there is a variable for discount_amount and discount_amount2, but not sure this will work as it only seems to give the option from the 2nd item on. Can I make this so it works for the 3rd item and on?

Also, can I give them the option to add the quantity directly on the same page as the product along with the button?

What you have in mind is possible however, it requires some custom coding and some scripting.

Here one example:

That was so helpful.

The discount variable only seems to work so that you can change the price discount for the 2nd and more items, so it doesn't quite work for me.

The first example is great though. I only wonder, my site is done in Wordpress and is there a way to integrate the coding there since much of it is in the header area?

As with any programming, there's various ways to do the same thing.

Working with WordPress is a totally different animal. Not sure how you can incorporate coding of this nature into WordPress. It's much easier with other sites and/or hosts.
