Price manipulation

I only needed this app to record a few voicemails at 10 minutes max. The app shows that there are multiple in app purchase available like option 7 for $0.99. However, the app is forcing me to buy $5, $10, or $20 and I do not need all that time. I was forced to buy time I will have no need for. App seems slow but is easy enough to use so I added an extra star.
