I've tried both options and I think it comes down to how much you are spending. For the lower priced guitars (so long as you find them in a shop first) it's a great idea. I've even bought a guitar online without testing and got a great price for a superb guitar (Kramer Explorer, Flloyd Rose tremelo, quad humbuckers, etc. Plays beautifully), but I did have to spend time setting it up...
I'm in the market for a steel strng acoustic. I have no idea how, but in our recent move I managed to completely lose my old one. How is that even possible?
Gutting..
It would break my heart, if that was me..... any way it wouldn't - come to think of it, they (3) would be transported by someone i could trust.....ME!

I think guitars (and probably many other instruments) have come a long way in build quality in recent years, ecpecially those made in Korea (which is a fair few) point taken that they are not built as well as the prestigious makes Gibson, to name one...I have an Epiphone G-400 (Gibson SG) made under licence from Gibson, which is Korean made...and i wouldn't part with it, it was made in July 2002 and it still looks brand new!
Get a decent effects pedal, play about abit, and you'd be hard pushed telling it apart from a Gibson SG, there will be perfectionists that could i'm sure, but to the average Joe (like me anyway) you cant....Has great reviews too - And seeing though Tommy Iomi played 'Paranoid' on the SG, to me - when playing it, sounds close enough to me...

To come back to topic, i assume, as it was made in Korea, logistically it didn't come here by being delivered by a stork wrapped in a towel... so how it is packed plays an important role.
Same story goes for my Ibanez, although it has had some money thrown at it - in the shape of 2 x Paf Pro Dimarzio's & 1 Cruiser Pickup in the middle...also Dimarzio, it was taken from the shop staright to a well known Luthier to have it sorted, end result....bliss!.....£750.00 lighter, but for a guitar that worth that much, its a big risk being entrusted to postman pat (or his cat) but that may just be me.
