Buying from an aggressive salesperson
As described by the other answers, there are pretty harmless explanations for that behaviour. You could be slightly worried because he gave you exceptionally good deals for both instruments, but that's neither here nor there. Maybe he simply prices all items way up to be able to give a great discount on either sale. You can't ever know; the actual price you pay in the end is what counts. What I would do: If I expect in advance (or if I notice during the negotiation) that I am put under pressure in this way, I usually try to do exactly the same, in reverse. That is, I take  a minute to explain up front that I will not, under any circumstance, buy right now, but that this is a purely informational event. I will make sure not to have my money/card with me. Any high-end salesman worth his sale should have no problem with that at all. Money aside, you are shopping for something that will mean a lot to you. The salesman is not some peddler of arbitrary wares. Everybody understands that not only do you not want to pay too high a price, but also that you want to really get the item you want, and want to be happy with it for a long time. This is a tough decision, often, and if the salesman cannot, or does not want to respect that, then it would be a clear signal for me that dubious things are going on. In fact, you would probably be unhappier if you got the wrong item for a great price than if you got a great item for a slightly too-high price. That is something you should probably not tell the salesman ;), but can keep in mind. So getting the greatest deal of all times is probably not so high on your priority list.
