Recieved a mailing from amex for various Christmas offers. http://www.amexnetwork.co.uk/christmas
In in was one for argos, free £10 gift voucher when you spend £60 on toys and pay using your amex card (you need to print off the coupon from the internet and take in) This also combines with the current offer that argos are doing £5 gift voucher when you spend £50 in store.
After the store phoned up head offer to check that the offer existed as they havent been briefed on it.
At first the store told me that i couldnt get both offers but the till prompted the cashier to give the £10 gift card for the amex purchase it then prompted them again to then swipe a £5 gift voucher.
The amex £10 argos gift card was valid for 3 years when printed. The £5 gift card is valid till the middle of january.
