Hi hubby wants to go and see a travel system that a nearly new and going cheap to be fair it's a good one but I'm only 5 + 4. We do have to be very careful with money and I get why he is trying to spread cost particularly when this travel system is so good. (Its mama and papas 5 into 1. For 50.00 but only used a couple of times) any thoughts? I'm worried about bad luck and tempting fate x
