I ordered a heater and 5 step indoor step ladder at about 4.30pm yesterday.
There was a delivery available for today or next week for the same price, so I chose the delivery for today.
18 hours later and they arrived!
That's impressive by anyone's standards!
I emailed Quidco at 1.01pm today and I had a reply literally a minute later (1.02pm) to say my query was being looked into and that I'll hear something about my query from them within the next 24 hours! It wasn't a standard reply either... totally individual to me and my question!
I'm starting to approve of both Argos and Quidco!
