We'll match a lower advertised price from another New Zealand retailer on the same item (same brand, model, colour and size). Clearance products are excluded.

Found it cheaper overseas? Send it through anyway. Once GST and freight are added the gap often closes, and we'll compare it on a landed-cost basis.
