Thanks to everyone who shared this. There have been nearly 10,000 downloads since Valentine's Day. And, as is the case when there is a huge surge, I have come across a few bugs. Version 1.5.1 is waiting to be reviewed by Apple right now to fix a few bugs, among which the biggest is the issue of coupons printed to the full size of the paper they are printed on and using way too much ink. Also, since it was so hugely popular, I have left it on sale for the foreseeable future, so if you missed it last Friday, you can still get it today!
