Lipton ice tea

I love the flavour of Lipton ice tea and I've got a couple of bottles on one of my grocery orders but I'm after storage instructions please.  If you're not going to drink them straight away, is it better to store them in the fridge (like fresh juice) or at room temperature (like pop) please?  It could, potentially, be several weeks between getting them delivered and drinking them so would it be better to take them off the order until I know that I'll be able to drink them the week that I buy them please?

I'm happy either way, I just don't wanna literally pour money down the drain if they've only got a short shelf life is all.
