I've hit the big time

I bought a Twirl on Saturday on my lunch break. I don't normally buy Twirls but I really felt like one. The craving paid off big time. Cadbury are running a 'Score a Freebie' promotion where '1 in 5 WINS' (not 'wins' but 'WINS') a free bar. To my delight I found this on the inside of the wrapper:

I redeemed my free Twirl on Sunday and once again won, or as Cadbury would write WON, a free Twirl. This has also happened to another person at work. I'm starting to think we got the motherload box of winning Twirls.
I plan to try my luck and go for a third free Twirl when I'm back at work on Thursday. I'll keep you posted.
