Me: so there is basically 2 solutions for that problem. The first will take X days to be implemented and will cost you $Y. The second will take W days and will cost you $Z. Which one do you want?
Client: After analyzing your propositions, we need the 1st solution for about half our users, and the 2nd solution for the other half of our users. That’s a good news, right? Since only half our users need each solution, can you do it at half the price? It should take you only half the time.
