Having read the previous money saving posts I have a few tips for maintaining a social life with no cash!!
We v rarely pay for cinema tickets, nectar points from sainsbury's provide free Vue tickets/ 1000 points, and Diet Coke are currently running a promotion for Vue and Cineworld cinemas. The latter is a draw for 2500 free tickets a day -- which is a hell of a lot. Thus far i've put through five codes, and got three free tickets. However, the two occasions I didn't get a ticket I'd already put one code through on the same day. So I suspect that the vast majority of the time if you put through one code/day you'll get a free ticket...........
From the last three codes I put through from approx. £3 of diet coke I have £13 of free cinema tickets (and a drink to smuggle in when I go!!!)

Thanks for the tip - just got two free tickets via Diet Coke!
