This is my first year coordinating Confirmation prep at my parish and after some extensive searching this past week for gifts to give my teens, I opted for a keychain. I did want something religious in theme since I think that's important plus I wanted it to be something useful/practical.
So, after googling Confirmation gifts, I settled on a keychain. The one I really wanted was backordered so I went with a silver keychain from The Catholic Company that had a verse from Jeremiah 29:11 "For I know the Plans I have for you". There was also the option to engrave on the back which I probably would've selected if it weren't such a large group for which I'm purchasing, since it seems like a nice personal touch.
On a whim, since I didn't really think I would find anything for this website per se, I also looked at www.retailmenot.com (fabulous website for discounts, if you're not already familiar with it!) and came across a 15% off.
Hope that gives you some direction, Good Luck!
