would give minus 5

whoever built this does not know the royal mail prices in any shape or form. the lowest price it comes up with is for a parcel at over five pounds. According to this app its costing me more than mt actual product. Just to let you know it cost ￡3.66 to send a small parcell up to notice this bit “UP TO” 500g not ￡5.30 for 250g parcel. the only people who have given this 5 stars must be very shady people that like making a profit by over charging for postage. shame on you.
