Hey, the price seems to have changed since last I checked!
Yeah, that may happen. If you don't like this price, drop me a line and let me know what you think is reasonable and I may just alter it for a while.
Several users have indicated that they wanted a simple way to donate some money in appreciation for my free apps, so this is my way to make that possible.
If you prefer you can also send me some beer money by PayPal.
