Instructions:I got a leaflet instore that gives you a £10 coupon free (NO MINIMUM SPEND)for recommending a friend, filled form in and sent off and what do you know.... got a voucher through the post.
Done this again and got another voucher free with the same code and when i phoned to place an order she commented that it was a new code. I've done this three times now and never had a problem.
If you do this (via the leaflet from instore) you can also spend the voucher in store. NOTHING stopping you from using it both ways.
FORGOT TO ADD THAT POSTAGE IS £3.50 HENCE THE REASON THAT YOU ONLY GET A £6.50 SPEND FREE
