I was working yesterday and was surprised to see my Petsmart got some Emporer filters in cuz they hadnt carried them for over a year or more and then i looked at the prices and i wanted to have them all. Emporer 280 was $30, Emporer 400 was $40, when they usually cost $80 and $100 here in canada. I asked the manager if those prices were right and she said "yes they are a special buy because Marineland isnt making them anymore." Now i havent read any articles that also say this but it could be true and Marineland might be comin out with something flashy in the next year.
