WH Smith are doing 30% off OS maps on line or buy one get one half price in store.
I've looked into this.
It's only a bargain if they have the 2 maps you want in the store.
An OL Explorer at £6.29 and a 2nd one for £3.15 = £9.44, which is £4.72 per map.
By comparison, I have just bought a new Explorer from Dash4it for £5.89 with free postage.
It's not a bargain if you order a map online to be delivered, when the postage charge is £3.29
So a £6.29 map + postage = £9.58,
or 2 maps at £6.29 + postage = £15.87, which is £7.94 per map.
But are they going to give you 30% off both maps in the store, or will it be one at 30% off and one at half the full price?
