Hello Steve,
Welcome back!
Thank you for your question about your credits and balance. The short answer is that you can see the credits in the upper-left corner of your main snipe page. The snipe you have set currently uses a low lead time, which indicates that it is using your credits.
Yes, we changed the payment system years ago from "balance" (where you made "deposits") to a choice of "subscription" (unlimited use) or "snipes remaining" (pay per use). Customers on the "balance" system stayed on it until the balance reached zero.
A few years ago, we had a fraction of our casual users still on the "balance" system, like yourself, with a very small balance --- so we converted the "balance" to "snipes remaining"
You've been with us a long time. Please let us know how much you plan to use the site in the upcoming months, and we can extend the service a bit more.
