KosherBacon, I did exactly that!
I blogged a booklet giving me two 20% off discounts and bought one pair of mojita sorbet in black and got 20% off.
Then I ordered into the store a pair of taupe Moonlit star. When I collected and paid for them I also bought a pair of mojita sorbet in tan so got got 20% off of those.
When I paid I was given another 20% off booklet with two vouchers so am returning to buy another pair of boots, not sure which ones yet and they have a lovely man bag which I am tempted to buy too!
The vouchers are grrrrrreat!
