I've had these twice. Not bad really, it's quite good to get a surprise box of things. The only things I didn't ever use were a couple of bottles of something alcoholic which had spices in it or something and some cans of beans ( not the baked kind ) It's not worth full price, but probably worth a go at this price.
It should be ok as I have used discount codes in the past and still got the cashback. However, I suppose there is still a small risk.
TCB does not allow the use of discount codes.
do not forget to unsubscribe for the next month (popcorn)
Probably just get a load of junk which will sit in a cupboard for years
