Excellent, PGP is essential. A localbitcoins BTC purchase is fine, but please tumble your Bitcoin using BitcoinFog before sending them to Silk Road. I wouldn't normally recommend this as being necessary for such a small amount but using BTC that is purchased in person to purchase a vendor account, I would rather be safe than sorry! BitcoinFog: http://fogcore5n3ov3tui.onion/ Read more here - http://bitcoinfog.com/ Regarding the samples, I would recommend offering samples to people here with a relatively high post count and a good history of reviewing products for other vendors - their opinions generally have more weight with the community than the opinions of others where product quality is concerned. State your requirements (previous reviewing experience that they can link you to, minimum number of posts etc.), get people that are interested in samples to post here saying so, post the list of accepted reviewers here, then ask those members to place an order with you through your vendor account for the samples. I have to decline your offer of a free sample due to my position as a Silk Road staff member, but I appreciate the gesture. Best of luck! Libertas
