Not really sure what to say other than see title. These 3 items seem to be bugged on my side. Friend and my other client sees nothing wrong with the price. Removing the item and putting it back in the store didn't help, nor did resetting the store. I don't know if the items are also bugged in some way because of this, or if it's just the price disappearing on my end.
It's a visual bug that happens sometimes where it reads the price from some entirely different part of the item. Reclienting should fix it.
