Hope this is the right place (if its not, please tell me where to ask this):
Conditional Logic Does this solution allow me to add or subtract options based on another, previous selection? example: If user selects "4 wheel drive" offer the offroad package, other wise do not make it available"
Instant Updates Does this solution display instant price and configuration updates on page as selections are made?
Basis Components Does this solution allow me to price based on grouped product? example: If the user selects "4 wheel drive" subtract 4 highway wheels and tires, add 4 offroad wheels and tires. Price = -(100*4) -(125*4) +(175*4) +(150*4)
Thanks in advance!
