# Surprise! Pay $1000 > Source: > Published: 2026-06-09 17:32:57+00:00 My turn [writing for the Forestwalk blog](https://forestwalk.ai/blog/surprise-blacksmith-costs/): Now typically, when you try a SaaS product for free without a credit card, and you hit the limit, you get cut off. Also known as “disruption to your service”. Instead, we were invoiced $1000, which was immediately overdue. Genuinely curious how common this practice is. Just because I was surprised by it, doesn’t mean it’s unheard of.
