Sent western union payments to purchase legal research chemicals, first for the products, next for deliverer insurance, next for electronic rx for controlled substance (which they would issue). Attempted to get pmt for 'stamp' of some kind. Quit the cat and mouse pmt game at this point. Paid over $300 and got nothing. Money was sent to littoral, Cameroon (Africa). Unsure if the website of the courier with tracking number showing delay for no EPCS was part of the fraud or not.
