They will send you a 25% of voucher valid for a week from the 30th March to the 5th of April.
They have a new for old coming up but this deal is better! You get a £10 voucher for your old shoes valid if you spend £40 or more. But 25% is more than that!
The current sale on boots isn't that good because the 25% will still apply to most of that, so wait and save yourself the money!
