I haven't purchased anything on-line but locally, within 30 minutes drive from my home, there are two Big Al's, a PetLand, Kind Ed's Pet Center (and numerous Petceteras, Petsmarts and large chain stores).
The Big Al's have impressive 2500 gallon shark tanks, Tuesday night 7PM "Feeding Frenzy" big sale in the store plus they feed the sharks. Fun to watch.
They have a grouper of some sort that has a head larger than mine. I had a staring contest with him about 2 inches from my face... Pretty intimidating. I had to disqualify him because he was cheating... no eye lids, that bastard!
King Ed's is amazing. (Don't go if you are claustrophobic... tight isles and packed to the rafters with ton's of product) They are a little 'Mom & Pop' shop but they carry an inventory of a store that is about 5 to 7 times it's size. Amazing prices.
It be worth a trip up from Seattle just to check it out. Not to mention the cheap Canadian buck (aka North American Peso).
