At the top of their page it says 10% off.
There's another discount for new customers. 15% off.
I have a £95 basket and the 10% is taking off 70p 
I did a live chat with them and they said that brands set limits on what discounts can be used.
Every item in my basket is from a different manufacturer so out of all of them only 1 allows a discount?
AIBU to find this very misleading?
You're emailed 15% off codes. It doesn't say on pages this item isn't eligible for discount, only tells you when you try to add the codes.
