I will try. Manufacturer-funded coupons, like this and the Hovis one, can be redeemed anywhere the manufacturer stocks the product. Hence you can go into your local Tesco Extra, pick up a bar off the shelf, redeem your voucher and take it home. However this may not be so easy in the Tesco Express around the corner, because may not stock the product. So the short version is: if you're in the shop, you've got the voucher and the shop has the product - you're in luck.
