Free shipping and prices much lower than hamilton and west.

I Got my box full today, there all CAMP zincs and not some cheap knock offs.

Another site is Boatzincs.com the prices are close and they also have free shipping. They also offer extra heavy zincs which will mean less changing during the season and they sell pencil zinc kits for specific engines.

BoatZincs.com (978-841-9978) – The Online Superstore for Zinc Anodes (http://www.boatzincs.com) is also a MA-based company. All made in the USA.

Thanks for that!
