Peter Vander Wall explains why prospects disappear after seeing your price: they haven't decided they want it yet. Get them to convince themselves first by asking questions like "Why haven't you done this before?" and "What makes now the right time?" so they arrive at the decision on their own.

Why do people keep ghosting me after they see my prices? You could be selling them a $5 thing. And if they haven't made their own decision that they want to buy this thing, they're not going to do it. And so this is the game of sales is leading the prospect to their own conclusion that they want to buy from you. So you're not convincing them to buy, they're convincing themselves. And you simply do this by asking the right questions. So not only just information gathering, but also asking, why haven't you done this before? Why haven't. What makes now the right time to look into this? Why would you even consider spending money on something like this right now? And as they answer these questions, they're going to start convincing themselves that they need to buy, rather than you having to tell them they need to buy.
