BRS is $9 too...seems you found a price gouger, Vio.
Vio, I bought my Hanna Alk regeants from Marine Depot for $8. I hope this helps.

Thank you,
BRS shipping go for ever, i guess i will order.
Saltwateraquarium.com has them for $9 also and if MD had them at $8 they are now at $9.Alot of local shops and online stores sell them for upwards 12 to 20 dollars. I believe brs and md are the only 2 with them for 8-9 bucks
