A banner, a theme, card styles and your own details, all from the Shop designer.
Every seller has a shop page at reloot.co.uk/shop/your-username. Open the Shop designer from your profile to set a banner (your own photo, or one of the gradients), a colour theme, the frame round your avatar, how your listing cards look, a tagline, a bio, your website and your dispatch time.
You can pin one of your live listings to the top of the shop. Your response time is worked out from your real replies and cannot be set by hand.
A dispatch time you set is a promise to buyers. Set one you can keep.
