If you add can't be measured so it's kinda invalid. Must be specific numerical value.

Since when do offers constitute price changes? You have shown zero evidence of the low end (which is retard-tastically low for this exceptional hat), and haven't shown any sales at all.

You can't use dupes. You also need to prove both ends of the range with sales
