The store appears to be offline. I've ordered a total of three times from ps, com, and have always had good communication with him and received my order within the same week of placing it. The quality of the material received varied, but i was always happy with the results of working with it, and put the variance in quality down to the nature of the plant/time of year for harvesting bark etc. I'm saddened to see some of the complaints regarding service and hope the business name hasn't been assumed by a scammer, or that there another crackdown on ethnobotanicals going on due to the increasing popularity of some of the plants.
In short, "caveat emptor!"
