Save up to 50% on food when dining out. I've had their 3-month trial and was impressed at the range of restaurants on offer - useful if you're regularly out for lunch anyway (e.g., instead of collecting Pizza Express vouchers, it's just 50% off all/most of the time)
Exclusive 1 week offer - repeated due to "popularity of their December offer". Expires January 21st.
Code = MS23
(sure you can keep signing up on the "free trial" that comes up every so often with a different address, but this is a good deal if you want to sign up "properly"?)
