Deposit Cash to PayPal with Android App

The recent update to PayPal's Android app

states that you can now deposit Cash into your PayPal account at CVS or Rite Aid. Once you have the latest update, you press on Add Money, select In Store Cash, select your store and you'll be presented with a Barcode to show the cashier. Once they scan, you hand over the money. After 15 minutes and after a 3.95 fee, it will show up in your account. 

Nifty idea if you're in a pinch. Are there any other services that offer such a thing?
