If you have any tmart points you can use them to enter their black-friday-sweeptakes comp, there are various prizes but the likely 1 to win is a $12/£7.67 off of $50/£31.98 coupon.
It might not mean anything but I’ve won twice both times at around 5am gmt, so may be a case of entering at the start of a new day for the best chance to win.
If you don’t have any points you can get some by signing up to their newsletter if you haven’t already and by doing reviews or uploading pictures for any previous orders
