I've recently bought a whole stack of gear and none of it at retail prices. In fact I nearly shot our local dealer who not only hadn't spent any time with me at all, (we'd been in and spoken so he new a huge order was coming) and when we made the first order he tried to charge over RRP. Unreal. I said why? What possible extra value was he adding? I'd done all the research, all he was doing on this occasion was supplying boxs. He had no answer, and we bought elsewhere.
Some of the best dealers offered great discounts. It is possible. And they're the nice ones. I'll buy from them again. They're not making their usual margin, but they're not having to provide their usual service either. I'm doing the install and research. So I expect to get a fair deal. I asked my speaker supplier if he was happy with the price and would still make a profit. He said yes, (20% off Dali) and we went ahead. Everyone was happy.
Now I happen to be a big fan of Richer Sounds and Superfi. They try very hard on price, but are not very good on high end hi-fi. For everything else they're great. Just don't expect someone to serve you with 20 years experience. But if you want that, pay the premium at an RRP dealer. It's worth it if that's what you need. I just hate being ripped off. If I'm not requiring their service and knowledge, then I want a good price as part of the bargain. A good dealer will oblige. Ring round a few. In the credit crunch, you'll find dealers a lot less snooty. This is a good thing. (Smart for them too as when the economy improves I'll recommend them and buy again).
That's my experience.
