Wilma, let me tell you a little story.
I found out about Tim Tams from an Aussie I used to chat with on MIRC. I was dying to try them. I searched specialty stores in the Toronto area without any success.
So, just over a year ago, I moved to the butt end of the universe. Sundridge, Ontario, population 1,000. It's located on Yonge St. (Hwy 11) about 3 hours north of downtown Toronto. It has exactly ONE grocery store, Foodland. Guess what?
It sells Tim Tams. Three different varieties: regular, dark chocolate, and caramel.
Let me know what your preference is, and I'll get some to you somehow.
As a matter of fact, I think I'm going to Richmond Hill tomorrow. Any chance we could meet up?
