Ok bear with me, when you spend £10 on Ariel, Fairy and a few other items at Sainsburys they give you 2x £2.50 off vouchers , 1 for Ariel and 1 for Fairy detergent
So today i bought 1xAriel Gel and 1x Fairy Gel and 1xFairy Conditioner for £10 which was all on offer at half price , this then gave me 2x £2.50 vouchers
I then went back and bought the same again and used the vouchers so it cost £5 and i then got a further 2x£2.50 vouchers
Also if you choose the Timmy packs of Fairy you can claim free Timmy Time books !
So did this 4 times, hope thats clear ?
