I got a shipment in from them just few weeks ago.
It did take longer than usual for them to ship out (last year when I'd order, they'd have the order in the mail within a few days, this time it was almost 2 weeks).
I'd emailed about my order through their website and they did reply by the next business day, though.
If you sent your email through your personal email, I'd go back and try through the website, in case personal email gets caught as spam?
You might also check on AquaBid's forum to see if there's any update- I know they do a lot of business there.
If I had to guess, I'd guess that they're probably not keeping stuff in stock right now, and have to wait for orders to arrive from FAN before shipping out? That's just guesswork, though.
