I don't really know if this is a recent problem, but I wanted to pre-order a product and I'm getting this message. Does anyone know if it's an error? is there any kind of solution? Because, as far as I understand, the A-on store website It is quite reliable and safe to buy and it's the only site where I can buy this pre-order :(

Sorry for my bad english, and because I don't know how to use reddit
