Dear Kam: Although it's rare to find two strains mixed together on the flower shelf at dispensaries, you can still find blends in several other forms. Extractors love mixing strains together when making different forms of hash, for both economic reasons and flavor characteristics.
It's very common to find rosin "strains" that don't exist as true cannabis genetics because two different cultivars were used in the extraction process, often chosen by the head hashmaker. This is essentially like a blended whiskey, except what you're blending differs based on strains, not age. Some of my favorite extractors in Denver create delicious terpene blends with their rosin, like In House Melts and Soiku Bano. McGriddle, an ingeniously named cold cure rosin blend of Donny Burger, Gelato Cake and Maple Dunks, being a recent example.

Infused joints are often made with two different strains between the flower and concentrate, too — and there are plenty of weed salads out there filling pre-rolls or discounted bags of shake at dispensaries, although those blends aren't as tastefully chosen, and definitely won't impress your nose or tongue.
It would be fun to see more pre-packed combos of flower, but most users have a hard enough time pinpointing a strain's characteristics as is. Adding one more will just confuse them. In the meantime, just buy an eighth or a gram or two of various strains, and mix it yourself.
