Worth noting- the $35 Chromecast dongle comes with three months of free Netflix membership (including for existing users), which makes the thing very cheap indeed.
Well that was close.... I also have prime so I figured I might get my chromecast quicker if I cancelled my order from google store which I made 4 hours earlier (I went with cheapest shipping).
Click through the confirm prompts to cancel my order from google. Click to buy from amazon, expected delivery date: 22nd of August.
Arrrrrhhhhhhhggggggg
Flick back to the google store tab and find that it has declared that I couldn't cancel my order. Phew.
So, Amazon actually said when Chromecast might ship by? When I was about to order it, it didn't give any indication of when it might arrive, it just said "we'll email you when we get an idea."
The Google play store guaranteed shipment by August 7, though, so if Amazon really expects it to arrive by late August, I'll just go with the play store.
"...you will recieve an email with a promotional code for 3 months of Netflix. Offer valid for previous, new and existing Netflix members, one per Netflix account."
