Tunze works different from most companies in that they print a catalogue in retail price and then as a dealer depending on your volume and level of service you get a discount. Anyway, the mail order houses all sell at MSRP, it is kind of a truce agreement amongst each other and one I have tried very hard to hold because my worst fear is a price war that would devistate any hope of having local dealers. I have long argued that competition occurs on many levels, service, proximity and reputation are every bit as important as price. I have seen over and over again product selling mail order for the same price they are wholesale and then they essentially dissappear from the market because no one is making any money on it. The product is too technical and too expensive to be effectively marketed without the customer seeing it and having assisstance. I notice LFS's sell a much broader range of items, the mail order houses sell hundreds of Streams, Magnets, Osmolators as well as brush sets and cleaning gloves but the LFS sells complete filter sets and skimmers and can more effectively explain why you shouldn't get a Stream and maybe you should get a 7400/2. So far I am reasonably satisfied, a bit frustrated with the lack of good, strong LFS's. In my shop we can and will fix just about anything, somenights I have 2 pumps and 3 light strips laid out to be repaired for customers- it seems that in general this end of service doesn't exist anymore. I cannot emphasize enough the need to support a good LFS if you have one near you, one where someone can fix stuff and has the knowledge and know how to help. I would like it someday that if your Tunze pump breaks you walk in to your LFS and it is repaired on the spot, I want service to be what puts us on top. In my shop Tunze is the lowest mark up item and we sell at MSRP but occasionally run sales on packages or bundles of equipment. The shortage situation has kept the price at around MSRP but I know some stores charge 10% over MSRP and others are more negotiable and if you are buying a kit they might be cheaper.
