Better from restaurant than store bought

I am not a tea drinker on a regular basis but find when I am feeling under the weather I enjoy a hot cup. I especially like the Honey Lemon Tea from Tim Hortons. It has nice strong flavours, which is what usually deters me from drinking tea, I find most I have tried to be too weak and not enough flavour. Instead of stopping at a Tim Hortons everyday during my last sinus infection, I decided to pick up a box of their brand tea. I was somewhat disappointed with this version though, it is not nearly as strong as what I was getting from them....not sure why. I may try 2 bags and see if that makes a difference.
