Tesco Instore - could be store specific, this was in Ipswich Copdock store.
Pack of two tape measures (measuring tapes), one 5M/16FT, one 2M/6FT
Reduced from an original price of £2.00 to £0.50
Fairly cheap quality, but probably ok for measuring stuff indoors. Both of them have a clamp button to hold the extended tape in position, and spring recoil.
