I never knew Argos had a birthday club but they do. Join The Birthday Club just now at Argos and you may receive an exclusive £5 off when you spend £20 on toys discount code. It's not guaranteed but there's 30,000 to give away, so I reckon if you sign up know you should be fine.
The good thing is, you don't have to use it online either, print it off and you can use it in store too. The discount code/voucher is unique to yourself and can only be used once! You must use the code by the 15th December 2014.
It's really easy to sign up, just click the link above and enter your details, plus the birthday details of your children, and in return Argos will send offers around the times of birthdays.
Also, as part of signing up Argos will enter you into a competitions where prizes include Merlin Premium Annual Pass for a family of 4, £200 of Hollywood Bowl vouchers, 24 adult & 24 child Cineworld cinema tickets, £100 of National Trust vouchers, £200 of Ticketmaster vouchers and £600 of restaurant vouchers.
