In my experience, putting something on "hold" means absolutely nothing.
case in point: I had a car wreck 4 years ago. After over a month of my insurance company doing nothing, I finally did their job for them so I could get my claim paid. I wrote a check for $500 so a dealership would hold the car I wanted for 3 days until I could come back with a check for the total price of the car.
Three days later I turned in the rental and walked 200 yards to the dealership and was told "sorry, we sold that car."
So these days, unless I'm ready and able to buy what I need, then and there, I don't go shopping.
