Take their daily survey for more vouchers
Here's your chance to take part in a free online survey on what you watch on TV and get yourself free vouchers to spend in Tesco in return. Not only that but you will get sent a survey each day and you'll get even more rewards for taking them. This is an amazing site - I love it! I stock vouchers up for Christmas.
They have 6000 vouchers up for grabs ranging from £2 to £1000 - redeemable at loads of places including Boots, Costa Coffee, Amazon, Starbucks and B&Q.
