When did you buy your pram?

Just a general question when did you buy your first pram? I'm 12 weeks and the pram we want has got a really good offer on, we'd save £250 and get the car seat too so it seems silly to miss! We want to buy it and store it at one of our parent's house so it wouldn't be in our home. But I guess I'm just wondering if we're doing this far too early or just take advantage of the offer?!
