i will say that while ritebrews prices are good once you factor in shipping it's not substantially different than buying stuff from the LHBS.
At the LHBS I would expect to pay $10 for the yeast, $2*17=$34 and not sure for the yeast nutrient so lets say $6. grand total: $50. I guess at least I didn't have to drive anywhere!
If you LHBS has that yeast. I did order grain too that I could have got locally but these days it is hard to do what I want when I am home so I would rather pay and have it delivered then drive around to a LHBS.
