I ordered this from a tesco store, My mother also bought one so we had:
£10 off an order over £50
Free Delivery to home
If you only want one set, there is a £5 off new orders code.
or £10 off orders over £60. Now The leaflet was instore, I have looked online but can't find it. So if anyone finds it feel free to post.
In total the price was £70 but with online price and discount the 2 sets came to £60. They have red ones but are out of stock at the moment.
Also included in the Clubcard bost so could be even cheaper or free :)
