This is an old discussion, but I just found it now through a Google search.
I strongly second MarshalN's suggestion, to allow people to choose tins if they want. It might even be a smart business decision to sell the tins at cost (as opposed to Teavana's business model, which seems to be to sell tins at an astronomical price).
I ordered a bunch of Adagio samples a few years ago, and I loved the tins. I used them frequently, gave many of them away, and still have one, and wish I had more. I was actually thinking of placing an Adagio and ordering more samples, both because I enjoy sampling teas, and because I would love to have more of those tins.
I was sad to find that the tins had been discontinued...and I think it is particularly bad form and practice that there was no announcement made that the tins were discontinued.
I know that people are buying the tea, and not the tins, but I think there is a certain degree of expectations that people form (and that are reasonable to form) if you regularly purchase a product, and you see no change announced from a business, and order it again.
I also feel that the current tins available for sale are inadequate. I don't want big tins, I want small ones. My kitchen is overflowing with 4 ounce, 6 ounce, and 8 ounce sizes of tea tins. On the other hand I never have enough 1 ounce or smaller tins. For me, I see this change as a major negative one, and a major deterrent to ordering samples from Adagio. I regularly order from Upton Tea Imports, and their samples are significantly cheaper than Adagio's. Many Adagio samples are $3 and some are much more. I also notice that teas of similar grade and quality that are sold by both Upton and Adagio tend to have pricier samples with Adagio. In the past, I saw the tins as extra value that made it more than worth the price premium to order from Adagio. These little things can be the difference between a purchase and no purchase.
