similar thread to this one. http://www.ozbargain.com.au/node/35529 But this time, u get 15 bucks to spend at SurfStitch online when you refer 4 friends and let them sign up. Im not sure when is the expiry date. it says this is the limited rewards. usually we have to get like 2000 beans to get a good rewards like this!
Sign up to Nescafe's "Cup of Rewards" program and receive "beans" to claim for rewards.
Get 200 beans when you invite a friend and they join the program
With 700 beans you get $15 to spend at SurfStitch.com. Get FREE express shipping with your order.
so basically, if 4 of your friends respond to your join requests then you can get the $15 voucher (maybe u can grab a flip flop or simple shirt with this 15bucks!)
Continuous Deal
