I feel like the market for fungi on the darknet is lacking in reliable, consistant US vendors. I mostly order bulk of Penis Envy exclusively, but the lack thereof has led me to pickup less potent strains of fungi which is upsetting. The vendors I've used thus far including mushroomgod and TheWisdomGoddess were great but their only flaws were how fleeting their stock is. I can understand not having an unlimited amount of stock but damn someone could be making too much money off me if they bring some consistancy to the table.
Consider growing your own as a nice hobby. Also check out TripWithScience's liquid. Extract should be tried at least once in a fungi lover's life. Can also be made yourself watch and learn http://youtube.com/watch?v=tVYhL16cYy8
