Right now you can buy Google Home Mini or Amazon Dot for £35 at Sainsbury and you can exchange £40 voucher with its double up point event, which effectively costs £17.5 in cash value. There are 4 google mini in shelf at Sainsbury's Longwater Lane Store but not Amazon Dot in stock. Therefore I bought 1 mini. Get it by 10pm before the event ends or it runs out of stock.
