Thanks a lot for your help!
I've done some research based on what you indicated and here's what I found:
- the style number on the label doesn't match the one on TB website.
- as you said the price tag is formatted differently.
Contacted the seller with photos enclosed.
He answered that it's authentic but was purchased from TB outlet in UK that's why the style number differs. Since I don't believe it's possible I've made a return for a full refund.
I wonder if I should contact TB with this question about style number because I'm hesitant what feedback to leave.
