4 oz. bags are a good way to get 2 really good pots of coffee to see if you like a certain roast. Also if you have lots of friends it is a great gift for them to remember as they would reflect on the source and rarity of the gift. For family members this is also a nice delicious gesture.
Any roast you would like is fine. I don`t roast it until you order it. There is a free shipping option in the U.S. if you order 10 or more bags
If you absolutely hate it i can reroast you a different one for free and get it out to you.
