Simple but well-functioning plugin

This does what it says, and I like that you can upload your own sticker (though suggestions for size would be helpful). I have a slight issue with the sticker placement (as did another reviewer), but that can be fixed. My main issue is that the “Sold Out” sticker simply says “Sold”, which is a bit misleading. I guess I need to upload my own sticker to fix that. If the wording can be fixed in the next update, that would be great.
Thank you.
