How many times can u visit a hifi store before it annoys the store if u plan on a purchase

As an ex stereo salesmen (many many years ago) it really depends on the situation.  If the store is empty I'd much rather talk to someone about the hobby and maybe learn or teach something.  If the you are taking away time from a paying customer you are infringing on my lively hood which is not OK.  If your respectful of others time and willing to build a relationship it could be beneficial to both parties.

I have read many of the BS responses you have received regarding placing a limit on visits or what is respectful for a dealer. You are obviously interested in their products. I would go in every day until you make the right decision for you. 

If you receive any BS from that particular dealer, I would buy elsewhere and then go in and show them the paid invoice! Also, ensure you get at least a 15% discount off retail since there is a 40-50% markup regardless of brand or what a dealer tells you. 

Lol personally I like to drop off a gift certificate for Starbucks or something like that. Lol when they like you they will tell you more information you should know. Likely you will gets at least 20 times your money out of what you paid for a few gift certificate s here and there. When they thank you pick there brain.

If you are there to genuinely look and learn, with an intention to buy something some day, somewhere, just let them know. Most dealers are understanding.

However, if you are not serious about buying right now, and just looking, they’ll appreciate knowing this too - and/or so they can go help others in the store.

Most are acutely aware of tire kickers and online shoppers. It helps to let them know what you’d like to do. Ya never know, sometimes they can work something out for ya on a purchase -and- offer valuable warranty support later if something goes wrong. My local 56-year-in-business dealer developed loyal customers this way. 

The approach that’s worked for me is to be courteous and professional to everyone, period. What’s really gonna wear on you is trying to sum up every potential client...I’ve been in the investment biz, owned my own mortgage banking company, and been a pro musician producer and sound tech and it never pays to be rude. You never know what's gonna be referred to you and if you think you do you're wrong.
