My friend told me about this,as she bought in OCT from school,as they get a percentage of sales for school funds.
But can be bought online,as this is valid from Oct to Oct,they are selling them with £5.00 off.
My friend showed me here's,it's fantastic,it gives you vouchers to use on tons of Resteraunts,McDonalds,Pizza's,days out,Golf tons of things.
She used here's once and saved the cost of the book £20 on 1st usage.
More details on website for offers and voucher usage etc.
