Hi all, 
I am attempting to create a survey analysing consumer choices in hypotheticals and am having some trouble with the survey design. 

The base idea is that participants will be able to choose three versions of a product at different prices. Each price will start out at a predetermined value, but when an option is chosen, that price increases and the others carry forward. For example: 

Options Q1:
A for $1.50
B for $2
C for $2.50
 

An assuming the participant selected question C, then:

Options Q2:
A for $1.50

B for $2

C for $3

What I am having difficult with is figuring out how to implement this. I can of course create every possibilty as its own question and use branching paths to create a web, but this would take a large amount of time, as that would require about 250 questions. Is there a better way to do this? Perhaps there is a way to automate this increase based on the previously selected question?
