I think you need to make a decision and go in one of two directions: * 25 (or maybe 50) card limit, and call it something like "Try before you buy" * 100 (or maybe 200) card limit and call it "Free" Basically either the free tier is usable for a reasonable period of time for a reasonable subset of your customer base, or it's a "free trial" to get people setting up and seeing the value without having to enter credit card details. If you go with the "free trial" approach, the precise wording for what you call it will be important. I put a couple of minutes thought into trying to come up with a good suggestion and "Try before you buy" isn't too bad, but there maybe a better idea.
