Hey there! I'm signing on for the next couple of hours to bring you the cool things I find that are actually on sale. None of that mess where a product was the same price last week, but it got inflated 20% for a day or two so it can pretend to be on sale. I look for the real sales.
For example, this luggage scale is down to $7. It's been at this price once or twice before, but I've never seen it lower and for what you're getting, it's a steal. This thing has a strap that wraps around your luggage handle so you can pick it up and know exactly how heavy it is. It's light and small enough to bring with you, and I've used one of these at the airport to show the folks at Southwest that their scale was in need of calibration.
You want one of these, and for this price there's really no reason to not have one.
