Active speakers. What to choose?

If you demoed the product at that dealer and used a lot of his time, then you owe him something for that service. It's wrong to price shop AFTER you have used his services to make your selection. On the other hand, I would tell him you want to buy from him, but his price is way out of line and see if he can at least get closer to the competitors price. And yes, he can keep your deposit, but if it's only been a few days, it's a bit petty on his part.

Ermm. I was buying through emails. And have not been to his shop. Thus " The cooling off period law". And it had only been within 24hrs.

And I am not even sure about his other buyer backing off. See he was telling me about his other buyers interested in getting the Komris from him when I wanted to put a lower offer for the Komris and when I expressed my interest in the Klimaxes, he took off his ad for the Komris. So basically I think that was his sales strategy.
Well I wasn't exactly price shopping, I saw a better pair of Klimaxes that have the latest Dynamik upgrade and a better finish in a colour that I would like better and at the same price.
Yeah I felt bad so I am perfectly fine with him keeping my deposit as long as he likes. But really I don't see how it will help him make the sale of the speakers better.
What I don't like is that he started sending me hate mails after I told him that I am going to check out the laws regarding this sale. I wasn't threatening him but just wanted to be thorough.
BTW I am only 22 so I don't have much experiences regarding this kinds of issues. I called the Federal Consumer Protection department and they thought that my case perfectly fits into the "Cooling off period law".
Another thing you should know that he pushed me into making a decision like oh the speakers will be unavailable to you on Tuesday because he has another buyer - I wired the money on Wednesday and called it off on Thursday. I should have known that it was his simple sales technique.
How many of you guys believe what he said though?
And was he right to say he will refund and later said he would keep the deposit? And does he have the right to force me into purchasing the speakers like he said he would if I "pushed" him?

"Cooling off law" is a law enforced by the US regarding sales like this and not by individuals. He didn't have me sign anything regarding the terms of purchase, which I really should have asked for since it was a big purchase. Because as you know those receipts must protect both the customer and the seller. He didn't allow me to exchange for anything, what I meant was if he carried other items of any value to me, I would have bought them.

He didn't offer to sell me something else.
