Sorry if this is an obvious answer question

I have prime and we are TTC this late summer. So, I am in search of a double stroller.
I'd like to order 2 from Amazon and test drive them both (in my house, not outside) for a few minutes. I won't be "using it", but I will literally put it together, roll it around, see how my carseat fits it and then packaging it back up.
With free returns, I will send the one I like least abck to Amazon for a refund.
Is this OK? I figure it is, but I won't want to cheat anybody by ordering 2, knowing I am going to test out and return one.
Again-sorry if this is a dumb question.

Also: will Amazon give me a hard time around returns? I've actually never had to return anything to them, in all the years I've shopped Amazon. I *really* don't want to be stuck with 2 $400 strollers!
