Seems like a decent price for this little set which is quite contemporary/quirky. Saw this when looking for a case for my g/f... upwards of £30 in a few stores. Delivery notches price up to £22.98, but still cheapest out there and good few quid under the RRP. Also still only £24.43 if you want to go through Amazon themselves.
NOTE: THIS IS FROM AMAZON MARKETPLACE SELLER "Base"...4.8 stars over the past 12 months (16132 ratings), so hopefully mods will let this stay.
£17.99 plus £4.99 delivery.
