They call those loss leaders, and sadly many LFS folks don't understand the concept or potential return.
Short-sighted greed. Thats why I only buy frozen food from the PetCo here on 88th Avenue by the Home Depot. Thats the only thing I buy from any LFS anymore.
Aquamart is overpriced on pretty much everything - including their corals. Went there once to buy some 24W T5 bulbs - took ME over an HOUR of searching the back room BY MYSELF to find 6 bulbs that would work. They couldn't even be bothered to help me find the right color bulbs - and when I FINALLY found what I wanted - the boxes so old they had 10yrs of dust on them - there was no discount - but the price tags had been stickered over and over. When I got home I pulled the layers of stickers off. Seams they retag everything occasionally - because I found a sticker on a 460nm 24W bulb that read $12.95 - but the price I paid on the most recent sticker was $25.
Liquid Kingdom used to occasionally get some decent coral frags in - but haven't seen anything good in over a year. Their tanks are currently full of flat works - zillions of flat worms.
When I asked the owner if he would offer a discount on the corals - due to the flatworms - he said simply, "Nope. If you don't like flatworms we have some chemicals you can use to kill them before you put them into your tank." Geeee thanks!! -- uh nope, you can keep your infected corals buddy! A bucket of Oceanic costs $65!!
Fish den has the grossest tanks I've seen. Never any cool corals. If they happen to have anything even remotely nice they want $100 for that coral. Staff is less knowledgeable than ME - thats pretty bad.
Bought about 100 snails and crabs from Sherman tank. 80% of them died. And trust me, it's not my tanks. I'm a neat freak and all my water parameters are spot on. All my corals are vibrant and growing. My other inverts are healthy and growing well. But for some reason, despite a long 8hr acclimation period at stabilized temps, most all those inverts I bought from Sherman have died. I've had to dig around and take dead snails and hermits out of my tanks to avoid nitrate spikes from the rotting corpses. Boil the shells, remove the cooked carcass and then put the shells back in the tanks.
The rest of them suck just as bad. :uzi:
I buy online and I don't give it a second thought anymore. I'll support the retailers who support me. Recently bought a big bucket of Red Sea Pro Coral and got the $5 shipping deal from 2 Docs. Also bought some rebuild parts for a canister filter that got dropped. You can't find an intake tube for a HOB canister at any of the local stores. "We can order that for you." Yeah?!?! Well I can order it TOO and it'll come to my front door in 5 days - rather than make a trip back up here to your store and pay sales tax on it ++ your markup.
Far as I'm concerned - the LFS don't exist anymore unless it's a dire emergency. They have nobody to blame but themselves.
