I set up a Merchant Account at the office for our website's PayPal.

There is one item...it's a book. I have the price, shipping and sales tax all entered in the Profile.

What I CAN'T find out is how I do entries/adjustments for orders of more than one book. If a person orders more than five books, the price per unit changes. 10 and above, another change.

How the HECK do I set that up?

Thanks!
