Travel system

So I just posted in another group on FB about this buuut want to ask you ladies as well...

I bought this travel system yesterday for $300 instead of only spending $139 on a cheaper one. My BF has the mindset “the more expensive the better” but is that true?? Have any of you ladies bought this car seat?? What is the difference between all of them??I’m starting to panic not only over this but also every time we go to a store I buy more “last minute” stuff we didn’t realize we needed! So $400 later... here we are 😭 & I still feel like I’m not ready!!! 💙💙💙
