Hello. I have a box inside a clear polybag with an FNSKU label that is incorrect. Will this matter as long as I put the correct FNSKU on the outside of the polybag? Thanks.
It would be a VERY bad idea to send in an item with the wrong FNSKU on it, regardless of what is on the polybag.
Yes it matters because warehouse workers will scan either one and get confused and it'll create all sort of problems for you.
Why is there a wrong sticker in the bag in the first place?
Just put your FNSKU "sticker" over the one in the poly bag.
