I just got one. (and I'm thinking of getting one for my parents)
I asked Sam's about shipping, they don't do it themselves,
but contract it out to a third party (locally), so shipping
rates will vary. And as far as I know, you can't mail order it.
I think you would need to go in and buy it at the store, and then
arrange shipping at the customer service desk. Not very high tech.
You might try calling to see if you can buy it over the phone,
and also arrange shipping, using your friend's card number.
It's pretty big, it's not going to fit in a sedan, I think you will
need a hatchback or pickup.
