Thank you, also excalibur for the answers. I rather assumed that this was a mistake. I don't understand why there have to be 2 codes on it. And for an article that is cheaper in relation to the other articles, this is in no relation to me. Since I wanted to have the back with a hot stamping, I am considering sending it back. The back should be shown on the homepage with the data codes and not without.
Actually, I was hoping to be able to exchange it, but when everyone is like that, it doesn't make sense.
But apparently I'm the only one she bothers.
You’re welcome! the Mxxxx is the item SKU and the BCxxxx is the date code.
