Adagio is my number 1 tea retailer!
I've used Adagio for years and have continued to be smitten with their products and service! The biggest draw of Adagio as opposed to other tea retailers has to be their focus on user participation. Users are able to create their own blends and add their own artwork to the packaging. This allows for mixes of tea that the typical tea retailer would never have in stock. But, because of Adagio's unique formula where users choose the individual ingredients, and thus, when the particular blend is ordered, Adagio puts together the mix as orders come in, it allows tons of customization.
