Step 5: Finding What You Want and Buying It
Once the price has dropped, visit the seller if you like, be friendly, tell them what a nice organ it is but it's a lot more than you can pay. You can't tell them the truth (it's worthless), they will just get mad. Let them know they can contact you later if they change their mind on the price.
The idea here is to keep yourself in the sellers mind for when the finally give up and just want it gone. This way it's a win-win. You get the organ BEFORE it goes out in the carport or out on the driveway to get all dirty and they don't have to pay to have it taken to the dump.
You may also come across the pragmatic seller who knows right off that it's worthless and posts an ad "come get it before I throw it out". Those are fine too, but please, don't pay anything if there is something wrong with it.
