Thank you to an applicant who informed me of the missing Paypal button!! Yes, the button is alive and isat the top of the "Application" page.
The only reason for Paypal is, aside from its convenience, it is fast. In the past, I cannot tell you how many times we had to return PERSONAL CHECKS because we just don't accept it. Now, no one will have to go through the hassle of running to the post office and changing a single personal check to a money order so that the application can be validated, etc.
That said, Paypal fees are expensive compared to purchasing a money order from US Postal Service (USPS), which I think is still $1.20. The downside is that if by chance the package gets lost, the money order is also lost (and a huge headache to retrieve its full amount)... which is why insured delivery is always recommended.
So perhaps, in the end, extra $5 isn't so horrible if you can manage to pay via Paypal and send rest of the materials via Priority (or First Class). In the end, we don't care how it is sent to us so long as we receive the complete package safe and sound... and I'm sure you feel the same way.
