Hey guys,
I thought that I'd pass this deal on.
Go to drsfostersmith.com and search for AGN-16882

Add the 160g reef crystals to your cart.

Use coupon code 35851700 for an additional $5 off.

Shipping for one bucket is $9.99, bringing the total for one bucket to $36.98 shipped. I think the shipping for multiple buckets is only $11.99.

Enjoy, I hope this saves someone some money!
