Wikileaf is an online resource for medical and recreational marijuana patients and consumers. You can compare marijuana dispensary prices and menu's as well as research cannabis strains. Wikileaf displays menus and prices for recreational and medical dispensaries in 7 states ( Washington, Oregon, California, Montana, Nevada, Arizona and Colorado). The company is headquartered in Seattle, Washington and has been dubbed "The Priceline of Pot." Although they have this nickname their price comparison model is what's called a "Reverse Auction." This means that the consumer specifies how much he or she is going to spend on their next marijuana dispensary visit and then all the marijuana dispensaries within his/her radius put forth the most amount (in grams) they can at this price point.
