It's amazing how often popular items seem to go out of stock if you don't play their game though. I used to own a model shop (down Zimmer) that specialised in high end radio controlled cars. It was a cut throat market with loads of entitled arseholes (otherwise known as customers) who didn't want to pay full retail but if you were too open with how much you were discounting it suddenly became very hard to get stock.In Europe you cannot influence the selling price due to strictly enforced competition laws. You can have an RRP but beyond that it is all upto the reseller, for any product. Any attempt to coerce reselers is considered anti competitive and is heavily punished and illegal.
