When you buy a $50 gift card at The Sony Store Canada before (and including) December 24th, 2013, you will receive a certificate for $50 off $150 worth of gift cards that can be redeemed between December 26th and January 5th. This is an in store deal only, but worth taking the time to get!
This deal is actually pretty darn sweet if you are planning a big Sony Store purchase come Boxing Day. I have used this deal before and it is pretty great. I suggest buying the gift card and then saving it, because you can combine the gift card you bought ($50 worth) with the $50 off $150 certificate you will receive. So, if you are buying something that is exactly $150, then this certificate is like a 33% off coupon.
I have a Sony camera and accessories for it rarely ever go on sale. On my wish list is this basic Sony External flash which is $199.99. If I use the method above to pay for it, come December 26th the flash will only cost me $149.99, so I save 25% off the original price.
