Ok, so today is the 20% off day for Marks & Spencer, but last time they did this, someone notice that there was a glitch and it was giving 30% off Furniture on the website.
At the time, I ordered a matress and got 30% off with free delivery. I've just checked again on their website and it's still giving 30% off AND it's also making an extra discount for the VAT which takes off another 3% (more than the vat reduction, but what the hell!!)
Just to make sure it wasn't a one off, I tried it for a sofa too and the same thing happened, 33% off.
Really nice discount for some quality furniture.
