We're happy to have sale items back for either a refund or exchange.
Our sale stock moves quickly though, so please note that exchanges aren't guaranteed - though we can certainly do our best. If you can see the size you're after in stock on the site, we'd suggest sending your sale items back for a refund, and buying the replacement straight through our website - that way you won't miss out.
If you ask for an exchange, we'll try to process this for you. If we're unable to do so, we'll refund you and send you an email to let you know.
