Proofer Proof Management

This app is great but they warn me I need to upgrade I already paid 9.99 for 50 orders and from my understanding this should be 50 orders that I use the app. Now I haven't used the app this month that much up to like 6 orders. And if there counting all my orders coming in should not be counted as they have nothing to do with orders. From the looks they have a great scam to make customers upgrade each time. Be careful with them if you check your orders also check the orders you have sent proofs and you will see what I am going through.
