The Sneakers Authenticity Guarantee programme protects SELLERS as well as buyers, as buyers cannot claim to have received a wrong or `not as described` item.
But now you are moving that from £100 minimum value to £200 minimum so sellers will not be protected under £200.
You have added the option for BUYERS to add the authenticity check for £10, why not for sellers?
I could choose to pay £10 for my sold items to be checked.
I wont be selling any more under £200 without protection.
Please either keep the value for checking at £100 OR give the SELLER the option to add the check for £10.
