I noticed that, too, did this one go up also?
Ken's prices are not that bad if he ships them to you first class for free from a state not too far away.
Ken's in East Peoria, IL (Central IL) and AFAIK he ships first class with a cheap upgrade to priority. Since he's centrally located in the US, first class should be fairly quick. A good option if you just want to try them out and don't want to buy a bunch of other stuff to make a $5-$6 shipping charge worthwhile.
