4 different prices pick one that has value.
I would like to know the best way to implement this feature into the add to card behavior. I have up to 4 different price values but only 1 that will actually be taken when "atc". Depending on which value has a number, sometimes other values wont have numbers.
1. price from the price_field_prod
2. price from a spot_price_calculation_prod
3. price from price plus percent field x spot.
4. wholesale when members are logged in.
what is the best way to add up values ? Do you think custom coded in php first and then have a final value to drop in the cart? or can they be done within ecart? How would you do it ?
