Boden have a leather trim Tote in silver or pewter metallic that is quite similar though slightly different shape - £59 less whatever discount you can find.
They have a silver leather tote that is more of a similar shape but very very silver plus £159.
Can't link as on phone.
Tbh I would just buy the dp bag (£15 with current discount?) and enjoy it for a season as IMHO metallic leather always rubs anyway even if you spend a lot
