For anyone that purchases bulk chemicals thru BRS, you may want to look at this link if you already haven't.

BRS sells on ebay... and here is the catch! Every week they put up 1 of each of their bulk chemical items like alk, ca, mg, gfo, and carbon. They put up a buy it now auction, but they also put up a true auction with a starting bid of about 1/2 price. The cool thing about this is that these auctions rarely get any bids, so 1 or 2 bids of a dollar or two over the asking price usually wins!
I just purchased 3.5lbs of the High capacity GFO that sells retail on the site for $99. With my member discount on the retail store, it would have been
$90... I paid $54 on ebay, starting bid was 49.99!
I also purchased a 5 gallon bucket of alk and ca for their starting bid of 34.99 each. These retail online for $70!
Just a heads up for those reefers on a budget(clap)
