Amazing M&S REN Skincare Offer

I did a little M&S order earlier on some REN skincare that I wanted and it came to £30 I've just worked out why it was so cheap and had to share it.

The kit is worth £40 and comes off automatically when you add it to your basket. The 20% comes off the whole order so you automatically get another £8 off your order due to 20% of the £40 freebie coming off too.
