I only just found out about this yesterday, but apparently it has already been running for six weeks.

From April 1st, some Kraft "cheese" Slices have promotional stickers on them, which are a discount coupons for ToysRUs, giving you $5 off your purchase, with some conditions and exclusions (see below).

The coupons are referred to as "Gift Cards", and are valid until July 24th, so there is still a little over two months left to find these and redeem them.
(they can only be used in-store, and on actual toy items... not pre-orders or actual gift-cards)
And you must be over 18 to use them, so bring a parent if you are a minor, just in case the store refuses to accept the Coupon from you.

The stickers look like this on the Kraft Singles products....


The top of the sticker peels off, and that is the part you take to the store to get $5 off you toy purchase.
(unfortunately, these are easy to peel off, so please don't go to the stores and steal the labels off the Kraft products... if you like the products, buy them, so that it encourages ToysRUs and other businesses to do more of these sorts of promotions)

Conditions can be found here, along with the following FAQs....

Where can I find a promotional Pack?
Promotional packs are available in Woolworths and IGA, Ritchies, Foodland stores during the promotional period.


When is the promotional period?
The promotional period is 1st April - 24th June 2018.


How do I claim my $5 Gift Voucher at Toys R Us?
All you need to do is take the on pack sticker into a Toys R Us or Babies R Us store in Australia. Select the products you wish to purchase, head to the checkout and hand over the promotional sticker to the cashier. The cashier will take $5 off the total bill.


I have more than one $5 Gift Voucher, can I use them all in the same transaction?
Unfortunately not, no change can be given. You may use 1 x $5 gift voucher, per person, per purchase.


What if my bill is only $5?
Then you will surrender the on pack sticker to the cashier at the point of purchase which will cover the cost of your products.


If my product is less than $5 will I receive change if I pay using my on pack sticker?
Unfortunately not, no change can be given. You may use the on pack sticker to pay, but it will be surrendered and not available for use again.


Can I use my $5 Gift Voucher online?
No, the offer is available for redemption instore only.



Can I use my $5 Gift Voucher to purchase Gift Cards or on Pre-Orders?
No the $5 Gift Voucher cannot be used towards the purchase of Gift cards or on Pre-Orders.


What is the last date I can use my $5 Gift Card in a Toys R Us Store?
The last date a gift card can be used is the 31st July 2018.


Note that they say July 31st on the FAQ page, but the Conditions page and the coupons say July 24th, so make sure you use them before the 24th, as the FAQ date is likely to be wrong.
The June 24th date they mention, is when the date they expect the promotional (stickered) products to no longer be available... but could be sold out before then.
There are almost a million of these stickers out there, at almost $5 Million of discount value for ToysRUs customers to use, so they should be on products for a little while, I would hope.

Note that there is no minimum purchase when redeeming the $5 Coupon/Gift Card, so you could actually get something for free if it is $5 or less. (you don't get the difference if your item is less than $5)
And there is no limit per day if you have more than one Coupon, but you do need to use one per transaction... so if you want to buy multiple items with these, just keep going back into the store and go through the registers with each Coupon.
