You can still buy the smaller packs of White Labs yeast at OBK. Different prices for some though. Yea, the price has almost doubled. I always do an over build with every starter. Still cheaper than dry lager yeast by far. I do 5 - 6 over builds and buy another pack of yeast. I paid $12 for WLP830 last month and it is now $16. Not sure when these price increases will end. I just checked More Beer and their same yeast is $16 also, Well, with our dollar being lower than the US dollar, our yeast is 30% cheaper.
