Here's a survey that we're working on.
12 products, two prices $1.5 and $2.5. The respondents will be shown a menu that have all the 12 products, with $1.5 each, and they must choose at least 4 out of 12. A bundle discount will be applied if they choose more than 4.
On the next menu, same 12 products will be shown, at a price of $2.5 each, same rule, choose at least 4 out of 12, get discount for choosing more than 4.
The client think it's a MBC project, while I'm doubting MBC it's the best approach because there's no price different between products on the same menu, so we're basically just testing the products not the price?
Please give advice, thank you very much!
