We're a start up in this space although more focused on chemicals. They have a quite a bit to do on the pricing front.

Petri Dishes, 100x15mm $133 vs. $79 (sterile, which is better) Amazon: http://bit.ly/I550u2 P212121: http://store.p212121.com/petri-dishes/

Allihn Condensers, 200mm Jacket, $85 vs. $43 Amazon: http://bit.ly/I5PC3p P212121: http://store.p212121.com/allihn-condenser/

It will be fun to see how they adjust moving forward.
