We talking buckets or boxes? I know the boxes (200g) IO at ER is just over $40 and the RC is just over $60. I want to say $43 and $63, respectively. Those prices are comparative to online, especially if you can't work out free shipping.

And on that note, I just looked and DFS has boxes for $40 and $48 with $6 shipping, but...there was some speculation about the RC (on RC too actually) coming from DFS, but I believe that was just the buckets and the lot had been cleared as far as quality, but who knows. Better safe than sorry with our tanks I say.
