I've never had much luck with Argos 2 for 3, but I'm going to try again!
Do I need to wait till after midnight to reserve (to pay in store) or can I just reserve tonight, then when I collect and pay tomorrow, it would be at the 3 for 2 price? Hope that makes sense!
Also how does it work if 1/3 is available to collect tomorrow, but 2/3 not till Fri?
