I have seen this used so the ad doesn't disappear. If you notice, this item is out of stock. They bump the price so you can see that yes at some point it will return. But they don't want to create backorders. If that makes sense.
Everyone needs a good raise with prices. Just priced a stick of copper yesterday and it was $50.00 plus tax. 2 weeks ago it was $45. It used to be $17.00. Looks like our raise should double your current salary.
