Hi there @Bapplepie,
Thank you for letting us know.
I can imagine you'd rather have a bag with the flavour specification!
All stickers contain a barcode, so in the first instance, it should have been attached to the bag to get picked and packed in the warehouse. But yes, it could be left behind somewhere accidentally. In that case, I assume you can find out which one it is when you look at the order content on the invoice.
But, to make it up with you; we'll send you an email to compensate the inconvenience.
