Foursquare + Amex = £10 back on £50 Tesco shopping!

Discount: Get £10 credit on your American Express credit card when you buy over £50 at Tesco (until 31 Dec 2012)

Hurray! Just saw this piece of news on my good old friend MoneySavingExpert.com and here is my plan:

1. Find my Tesco money off coupons! (I know I have one that is £5 off £40 shop, but where is it?!)

2. Download Foursquare - a free mobile app & sign up an account.

3. Go to the American Express website and link Amex to the Foursquare account just created.

4. Go to Tesco on Saturday (the superstore for a good selection of toiletries). Use the Foursquare app to:

- find the store 

- check in by clicking ‘Check in Special Provided by: American Express’

- then click 'Load to card' to load the deal onto Amex

5. Then buy enough stuff so that I still pay over £50 after discount.

Note to self: in the past it has taken over 4-6 days for the Amex credit to show up on Lloyds online banking...

I don't own Tesco or Amex...

====================== Update: 30 Dec 2012 ======================

So, I completed steps 1-3 and finally went to Tesco armed with a 6" shopping list today. Completed step 4 on my phone when I entered the store. About 3 mins after paying with Amex, I received a notification on my phone to congratulate me that I'd saved £10! Very efficient indeed!
