Found out this morning from an ex-buyer for Topps that it was made exclusively for them, so if you can't find a Topps that has them, then no-one will.
Metros of all colours are fairly common. Best you could do if you don't get the exact one is to take your tile to a few retailers and get the closest colour match.
Sorry its not better news.
Thank you for trying 🙂
