I'm designing an ACBC study that is a challenge in terms of how to handle price. Most of the features in the design don't make much sense for summed pricing, but there is one binary feature where if it is included, the total price would e about $175k more expensive in the real world.
The total range of prices applicable is about $150k to $450k, but I'd like to prohibit that one feature from ever being shown with a price below a certain point (maybe $300k-ish). All other prices would be set up in increments of $25k and there would be no constraints about features/levels tied to price values. It's just the one feature I can't quite work out what the best approach would be.
Any suggestions or considerations I should know? Would just having a hard rule where that one feature cannot be shown below a certain price point work out okay?
Thanks in advance!
