You might have heard a lot of this anyway But I am pram obsessed
I had an emmalunga side by side for twins,(hired from twins club, way too expensive to buy!) Way too heavy. then a childcare side by side, lasted til they were 4, and coz every time they got out they ran opposite ways, so I spent too much time saying" has anybody seen a child that looks EXACTLY like this one??" I kept them in the pram a long time.
Now I have a light weight 4 wheel stroller, that stays in the car for shopping, and a big three wheel jogger for walking around the town ( dirt tracks) its great to manouver, the best to push, but heavy and bulky to pack up ( so it just stays up by the back door). I also have a little umbrella stroller cheapie from target that we use to go on hols.
I have just bought a side by side jogger ,thats not too big. will probably still have to go through wide aisles, but hey all in all not bad.
As someone else recommended ebay you can get things a bit cheaper
