Varia Vue why no memory card included?

Just took delivery of a Varia Vue and surprised to learn there is no memory card included. You can 't run this device without it. Garmin don't make this clear on the web site, it's deep in the specifications. I couldn't find one to buy on the Garmin web site, so bought one for £7 from Amazon that turned up the next day.

Seems odd, £470 for this device, can't include a £7 memory card? Seems odd to me, is there a reason? Am I missing something?
