TK Maxx Identifying Codes

Brightone

Did anyone else see the recent Channel 5 programme about TK Maxx? For anyone who missed it, but who regularly shops at TK Maxx, it was interesting only because it revealed some codes on the price ticket. In the string of numbers at the top of the ticket (not the bar code) there will be a single digit with no zeros before it.  This is usually 1, 2 or 7 and they mean:
1 = Items specifically made for TK Maxx, so potentially a lower quality or a colour combination not seen in the brands own shops.
2 = Items that TK have bought from the brand which were once on sale on the high street and are now excess stock.
7 = Items that TK Maxx have bought from the brand but have kept in store for a time.

I have also seen a number 8 on items, especially recently on Gucci.  If anyone works for TK Maxx and knows what this indicates then I'd really like to know.
