This contrib works on product_info.php - I only use it where I've had different products on one page due to photo limitations (pre-printed catalog). I can't guarantee that it does anything other than print the actual price of items in the pull down, where they are different to the listed price. For example, I have one catalog page photo with three products on. I have changed a couple of locations to say 'Price from' instead of 'Price'. In the attributes I have created an option to choose between the products. One is the base price, the other two are more expensive. The contrib merely check whether the price attribute is changed, and if so, it prints the actual price in the pull down instead of +10.00 or whatever. It has not been tested with more than one option causing price differences, nor with any tax adjustments (ie flat price only). Hope it may be useful to someone. Nik
