I've never ordered from TFD and don't plan to (because I don't own a pet store), but what I want to know is what is their policy on shipping errors i.e. they ship the wrong type of dat? If they're good about correcting them, what's the problem?
See, their company being a wholesaler and all, I wouldn't really expect world class 'customer' service (as in the hobbyist). The middle man (your LFS) doesn't call needing all kinds of info, they know what they want to sell, they submit their order and that's it.
At the same time, I fully understand a hobbyists' precaution to get the order right, and see the quality of the stock before purchasing. The problem is, that's not appropriate when dealing with a wholesaler, no matter how you feel they should treat "paying customers" (a wholesaler could give a **** less whether they loose your one order of $200, when I bet they've got LFS's that have steady orders of $400-500 every month or every other month). Wholesalers aren't used to hobbyist mentality "I'm ordering this to put in my display tank", only the retail mentality "I'm ordering this to make a buck off it".
So, the burden of responsibility falls upon the hobbyist to be more understanding, and ask for the right guy... the guy that deals with hobbyists. If that idea offends you, well you're S-O-L.
Happy fish-hunting everyone!
