Might sound a little odd, but in my search for a Jager heater, I came across linens n things selling them. ended up ordering the heater from there, as shipping was only $0.99. Pretty good deal from an unexpected source. www.lnt.com
Also, when I purchased my used eheim 2075, it needed some parts. Found them pretty cheap on kmart.com. Another interesting find.
It appears to be a different company that bought the name rights. There is a company that bought Circuit City's name and "likeness" (I guess the red store thing and logos etc), so don't be shocked to see "The NEW -Circuit City-" in the future.
I ordered from them months ago. I got the hose hookup/shutoff valve, a set of filter pads, and a liter of ehfimech. It showed up 3 days later, packaged very nicely. No complaints on my end, just good prices and fast shipping.
