This extra special warehouse sale, at the lock-up of Islington interiors store Twentytwentyone, is a one day, once a year event. With whopping discounts of up to 85 per cent off ex-display and sample stock lighting, furniture and accessories we suggest getting there early. Very early. This sale has been known to sell out in minutes. Delivery company Keep on Moving will be on hand to help you shift larger items. And if you miss out, you can still visit Twentytwentyone's Upper Street store - it's on sale until the end of July.
