I've been looking for a small backpack to use while cycling and found this deal, read carefully how you can get it for £1:45.
Follow the link add 3 bags + sim pack (free delivery).
Total comes to £21:82
Use voucher TDXR-EMCL for £5 off
New total £16:82
Return 2 X bags + sim card to store reduces total paid to £1:45 + keep 1 bag
I'm writing this in a bit of a hurry but think all the numbers add up
