I will go to Harrods in a few days to get the AMEX/FS offer.
I have 10 Amex cards include 5 supplementary cards with my wife's name and have registered 10 different foursqure accounts, synced one by one successfully.
Can anybody confirm the procedure for me to avoid disappointed.
1. go to Harrods with my iphone and all 10 cards
2. logging in and out one by one to check in and load card with one iphone?
(no need to load one card and use the card to pay,then load another one....??)
3. go to one of harrods till, purchase 10x50 gift cards, but 10 separate transactions
4.say thanks you to AMEX and Foursqure to give me 250 pounds.

Many thanks.
