I saw the advert on their site as I was impatiently refreshing it every 30 minutes hoping for an update on the Z2.
I called them about 10 minutes later and was told "the system is not ready to take orders yet" so I left my details.
On a whim I called them a short while later again and they were ready to take orders so I specified I want the S5 with the Gear 2, got a verification sms, got a confirmation sms and had the quote emailed through to me.
About 2 hours after that they called me back again.
Now to wait for the package to arrive and then to check it's contents before signing
I called because there was no upgrade option available for the deal online.
