Is there a size? discount code right now?
Yes, there usually is. The size? app unlocks a 10% promo code, subject to its terms. Newsletter subscribers are also offered 10% off when they sign up. The sale section cuts selected lines further.
Trainers first, with a separate app for drops
size? sells trainers, clothing and accessories for men and women. Limited releases go out through a separate app called size? Launches.
Ways to pay less at size?
Emergency service workers also get 10% off full price. They verify through Blue Light Card, the Defence Discount Service or Health Service Discount. That offer skips sale items, so compare it with the sale price first. For anyone else, the app voucher code is the easiest saving. Students can check the dedicated student discount page on the site. Spend £80 and standard delivery costs nothing. Click & Collect to a size? store is free at any basket size.
