To get the tablet for this price you'll need to do two things as it's still listed as £199 at the moment.
1.) The item price is £199, so first you need to get the basket over £200 using electrical items only. I searched and added a car light bulb to my order for £1.04... link below.
2.) Now the basket is over £200 of electrical items (important that it's all electrical items or the code won't work) you can apply the following code TDX-KNHP for £20 off £200 spend on electrical items only.
Ask for it to be delivered to store and you've got the tablet for £180.04.
Hope it helps someone.
Also remember you get £15 free to spend on the google play store when you buy this!
To get the free £15 sign up for Google wallet (the £15 does not just appear) and add a credit card once the cards added the £15 will be credited then just remove the card if your unhappy with leaving it active for someone to rob.
