I buy my B-Ionic in the 4gal bucket from Championlighting.com. You mix in RO/DI water when you receive it. It is much more cost effective to buy it this way. I have not ordered it recently as I am still using what I received 6 months ago but it did take about 6-8 weeks to get it from champion lighting. This is just one option that is the most cost effective. My lfs sells the 2 part 32oz bottles of each additive for $30.00. I think I got the 4g bucket for $85.00. Major savings.
I buy mine directly from ESV - great prices and shipping. I started wtih 64 oz ($15 + change) to see if I liked it. They offer refil units of all sizes ( 2 gal at 31.00). http://www.esvco.com

Well, some of these prices you guys are quoting seem a bit high. Even the prices directly from ESV are higher than most online stores. MarineDepot has the 64oz pair for $12.49, compared to $15.15 from ESV. The 2 gallon from MD is only $24.99, compared to $34.00 from ESV. I'd say shop all the online stores and find the cheapest. ESV is not the cheapest, by a long shot.
