Hi 95sc, Yes, most vendors peg their products to the US Dollar, so the actual price in USD stays the same regardless of Bitcoin volatility, but it's value in Bitcoin will fluctuate. e.g. An item costs $100. If 1 BTC = $100, then the item will cost 1 BTC. If 1 BTC = $200, then the item will cost 0.5 BTC and so on so forth. When vendors price their product in USD then it's value in Bitcoin changes with Bitcoin's value at the time. Please note that Silk Road uses a '24 hour moving average' Bitcoin value rather than a 'last price' Bitcoin value. This enures that Bitcoin's volatility does not affect the market too much! Libertas
