First Item Full Price, Second Item 1/2 Price

[blamb2320]

I need help setting up the cart so that when a customer buys more than one item, the first item is set to the full price and the second one becomes half-price. I have used quantity pricing in the past to achieve this but it really becomes a nightmare. The way I did it before was say the first item was $100, then when they purchase the second the total price becomes $150, so I set quantity pricing for 2 or more to $75. The problem comes in if they buy three - 1 for $100 and 2 for $50 each. Then the price becomes $66.66 each and so forth - so to list it out is really cludgy and ugly in the cart. Is there a better way to do this? Thanks, Beth
