For all that use Hanna testers this might be of interest. A 4 pack of Hanna cuvettes sells for $21, which I think is ridiculous. C'mon they're small glass vials. Well while searching for another source I stumbled upon of all places Hanna, offers a 25pak for $25. The catch is if you don't order $99 of gear they charge shipping and not cheap shipping, $17 shipping. Another note these do not come with caps and are listed as syrup test cuvettes.
But if you do the math...
4@$21 = $5.25ea
25@$25 +$17 shpg = $1.68ea
