Get this $20 voucher when purchasing at Yellowtail Wine

Hi guys, thought this is quite a bargain so I post it here, hope this would be useful for you. So I just bought 3 bottles of wine at Yellow Tail Wine. There was a $20 voucher attached on the bottles and you can use it at the Iconic. You don't have to verify your purchase, just enter some details and they will send you via email. I just bought $21 clothes but only spent $9 for that, including shipping. Cool right? And you can also enter into some kind of competition, but I haven't tried that one. Anyway, if you're about to get some wines at Yellow Tail Wine, enjoy!
