I got mine from Goulet. I have my first initial, which I tend to use on the letter itself near the signature. I also have my last initial, which I use on the envelope. I use J Herbin wax, which I melt with a butane lighter (the long stick ones that you might use to light a grill, etc.).
It seems intimidating to use at first, but it is actually very easy and fun. It makes as big an impression on the recipient as the hand-written letter does. Goulet has a video showing how to do it. No experience with the other stores, but I'm sure they're fine too. No affiliation with Goulet other than happy customer.
