Hi Burke! (and Anna ^^)
All my boxes and cats do this when I set them for sale. Here's what I have found about it:
1. It's not necessary to select "Original" when you set the cat/box for sale. The permission by the creator are no copy so that default setting will, automatically, set the box as "Original" once you set the price and click on apply. This way you eliminate that extra unnecessary step.
2. Once you click apply, the touch buy option will be enabled but only for you. If another avatar touches the box they will get the Info printed in their Local Chat, not the Purchase with one click option you get. I have tested it, I am sure of it
If they wish to buy it, they must right click and select buy.
The only way I have found to get rid of the touch/buy option after you set it for sale is to right-click and select Touch from the menu to access the cat/box's menu and then change the format (if it's in Box form switch to Image mode, if it's on Image, change back to Box) then toggle back to the preferred display method (Image/Box). WARNING: this will uncheck the "For Sale" option so you need to set it again. It's a pain, I know... but I have played with it for a while to try to work around it and haven't found a way to sort it out. None of the other options in the cat/box's menu removes the
The good news is that the touch/buy with one click once you set the box for sale happens only on your end and your costumers will be able to access the info when they touch the box/cat without getting the one-click buy option
I hope this helps :^)
