When you compare in online mode we add each store's typical delivery charge and check its minimum spend. Some stores let you check out under the minimum for a small extra charge – we include that; others don't allow it, and we'll tell you how much more you'd need to add.
Delivery charges vary by time slot, postcode and delivery passes, so treat them as a guide. Aldi and Lidl don't currently offer online grocery delivery, so they only appear in in-store mode.
