I'm looking at getting this TruPrint app from cydia. It says I can purchase the package for $9.99, but in the upper right corner it says I can install and it doesn't ask for any billing info. But there's also blue text indicating there's a free trial. What's going on here? Is it free? Do I pay $10? Or can I get a trial that expires? So confused... Please help me decipher what's going on!
