The last place I would drive a hard bargain would be in a bike store.
For one, I can afford the bike + extras, otherwise I wouldn't go out to buy it, we're talking relatively small money here. I simply set a budget and didn't exceed the budget, which may have influenced my choice of bike but that's fine.
When I went back a few weeks later with a small problem (crank play) the guy instantly dropped what he was doing, fixed the problem immediately (obviously no charge) and asked how my kids liked the bike. We talked for a bit more and he asked me to come in any time there is anything wrong with the bike right away.
I love the bike and that guy running his small business.
I wonder how he would have treated me if I had decided to haggle with him over the price of the seats or the bike using my negotiation skills. Relative to my income that guy is working a lot harder for a lot less.
Maybe my perspective about bike store owners changed when I worked for a bike store when I was 15 (newspaper route + working in the bike store paid for my first computer).
Car dealerships I approach in an entirely different way.
If you get treated differently if you have issues in the future because you bargained then that's an issue with the business not the price you paid.
Btw, I paid full price for the bike as it wasn't on sale. My guess is they made 30% profit from the $800 purchase.
