In store only.
Boots are having a HUGE summer clearance - the reduced items are now 90% off the lowest marked price. Some items have been reduced to 10p.
Also, childrens clothes are heavily discounted - eg T-shirts are reduced to £1.
Obviously stock will vary from store to store, but at my local store there was a lot of moisturisers, fake tans, hair accessories, mother and baby items, and some toys left.
Good luck !
