Instructions:Orange are giving away 2 for 1 meal vouchers as part of their Bright Top Ups deal. Just top up as usual and keep an eye out for a text. 1 in 3 people win an 'Orange' prize (free texts etc) and the non-winners get a 2 for 1 meal voucher.
Apparently there are various "non-winner" prizes, but I seem to keep getting the meal voucher. Works at loads of pubs near me though, and it's free, so can't complain!!
