From the S-1, this is a 68% COGS business, meaning their unit margins are 32%. You can debate whether some of their opex belongs above or below the line, but let's assume the 32% number is baseline credible.
The business had 4.1 orders/customer last quarter with an average order value of $57.23, meaning 73.21 of gross profit per customer. That means they recoup their marketing spend in 6 quarters.
The big questions, in my mind, are (1) will people continue to be customers after a period of time and (2) will CAC stay the same, rise, or fall? I think there's more room for disagreement here than people admit. I haven't looked too closely at their IPO pricing, but there is some amount I would pay for a share of stock in this company - it's >$0. I'm just not sure how that number compares to the current share price.
