Hey guys, I got a tough one. I've been researching for days, weeks even, to try and solve this. And I'm sure I'm going to kick myself if/when I get a solution. I've set up an ecommerce website from scratch (no prestashop, oscommerce, none of that), and I need to figure out how to decrease price on quantity. Ex; Umbrellas are $12.00 a piece. If you order 2 dozen (24) Umbrellas, they are only $10.00 a piece. I can't seem to figure out a way to make it work.. I have set up in my database the following columns. p - base price ($12) p1 - price after first increment ($10) q1 - quantity of first break (24) p2 q2 p3 q3 Hit me with your best shot.
