How can a niche subscription box test pricing without alienating customers?

[GraceAT]

I run a small e-commerce business selling specialty artisanal goods, and I've been struggling with pricing optimization for our new subscription box; our current model covers costs but doesn't leave much room for profit or marketing, yet I'm worried that raising prices will scare off our early adopters. We've done some basic competitor analysis, but I know we need a more data-driven approach. For other small business owners or pricing analysts, what methods have you found effective for testing price points without alienating your customer base? How do you balance value perception with necessary margins, and are there specific tools or frameworks for modeling how price changes might impact conversion rates and customer lifetime value in a niche market?
