... I do not readily see a store/unit number in front of a business - commercial/industrial. Most often, one has to drive around the block to come back - in the middle of heavy traffic - to guess where the company might be.
... Vendors do not provide a manufacturer's model number and pertinent information that affects item price. Most of the time what appears to be a bargain is the cheapest, outdated item model. These secretive companies have the information but do not disclose it for obvious reasons.
... Companies drop an icon on your computer and then have it running in hidden fashion in such a way that you cannot uninstall the annoying - usually popping up app. When you finally find the way it is only for the company to know and/or a helpful forum. There ought to be a law!
