There is a sign -£ so I put the discount amount
(-£9.50) then it says in red “ invalid discount amount, enter discount less than £0.00 (postage and sales tax)”. If I add a - after the -£ (-£-) then the 9.50, it says ‘invalid format’. How am I supposed to give the discount? I have offered cash in the parcel but not yet agreed to this.
