"During our Massive Home Sale spend $100 or more between Thursday 15 and Wednesday 21 March 2012 and receive a BONUS $10 voucher to spend between 22 and 28 March 2012."
The catalogue says the sale is for 2 weeks until Wednesday 28th March, so you should be able to use the vouchers during the sale…some decent deals in the there too:

My plan…buy a few hundred bucks worth of sheets and towels to keep the missus happy, and use the vouchers the week after to buy some Xbox M$ points :D
Nice one. Cheers OP
