I love Davids tea and I'm so glad to see that Calgary has one now.
The guy helping me today was super helpful. He spent a lot of time with me determining my likes and dislikes, letting me smell all sorts of their seasonal blends. I came in looking for a specific tea that a friend had given me that I thought she had bought from Davids. Unfortunately they didn't have it but I still walked out with two new flavours to try.
Their tin deal is pretty good. If you buy 100g of tea you get a tin for $2. When you bring the empty tin back and buy another 100g they give you $0.50 off your purchase. After 4 purchases the tin pays for itself.
Though this location is a little smaller than the one I frequent in Toronto, I find their tea selection to be great but their accessory selection to be slightly lacking. They carry all the basics that you could need, but the selection could stand to be a little more bountiful.
Go in here if you're a tea lover you're sure to fund what you need.
