Personally, I would do in store shopping, they have them on display.. see if you like the layout of the keyboard (very important).
I bought mine at Bestbuy.
They have a rewards program, gives like 5% back.
With that 5%, buy some extra supplies, maybe ink cartriges, or cabels to your TV.
But, choosing my laptop in person, was easier.
Because, you'll see and feel it in person. Get to "play" with it on display.
And , then to chose the right one for you.
