How much is the parcel app?

I'm curious to know, what exactly is the pricing structure for the parcel app? Is it a one-time fee, a subscription-based model, or are there different pricing tiers based on usage? Understanding the cost will help me determine if it's a viable option for my needs. Additionally, are there any hidden fees or additional charges that I should be aware of? Clarifying these details will assist me in making an informed decision.
