I dropped by the shop in the local mall, just to make sure that they still had the sealing wax and seals. They did, and they also had a small flyer with the website of the company that makes them.
Go to: www.nostalgicimpressions.com
and you'll find a company that makes seals, sealing wax, and even will make you a custom seal with the initials you specify.
For the bizarrists, there's a seal of an ankh and another of a Celtic cross.
They're located in the US, so overseas customers can order from them, but the cost is high.
