Swap prices in Ubercart based on Attribute price I am implementing a down-payment/multi-pay option on a higher-priced product, and I want to offer it as an attribute. Let's say the product costs $1,000... I want to be able to offer it at full price like a normal product, but also offer the customer the ability to only pay $500 at the time of purchase. If they choose that $500 option/attribute, their card will be charged for five additional monthly payments ($100 each plus a service fee amount, via the UC Recurring Payments and Subscriptions module) so that they pay the full amount plus fees over that time period.

By default, the Ubercart product attributes simply add their dollar amount to the dollar amount of the product. How can I use the attribute dollar amount instead of the product's dollar amount when that attribute is selected? One workaround would be to add a "no, I want to pay the entire amount now" attribute and price it with the normal product price, but that would not be ideal.

Thanks!
Looks like the Ubercart Ajax Attribute Calculations module will do the trick, at least somewhat... it will change out my product's "$0" base price for the attribute price, but it still does not technically "swap" the prices.
