I personally get my Blue Mountain coffee from Lina Coffee Roasters on eBay:
http://stores.ebay.com/linacoffeeroasters/

GRADE 1, ROASTED TO ORDER, 100% PURE AND NOT A BLEND! Wallenford Estate is the largest, most reliable, and most trusted processor of coffee in Jamaica and it is the most recognized and sought after brand in the world. http://www.linaepicure.com/JBM-Walle...ctinfo/JBMW21/

I get the 4 pounds and a bonus pound for $89, free shipping.

Top notch coffee.
