I do assume a lot of things. I do assume Amazon.com and most other major online retailers are implementing proper security. 3G/4g is more secure than an unsecured wifi connection, but it also come at an approximate cost of $360 a year.
So the bigger question is how often do you(a generic you) think you will find yourself wanting to transmit confidential information, at random public locations to websites that you dont inherently trust? And is that convenience worth $360 a year?
And I've actually personally considered setting up a VPN so I can direct my own traffic securely back to my own network, but even with no added expense, dont really see any logical justification for it.
