I’ll admit I had this mindset at some point, then I did the math that between a local lumber yard that will deliver pretty much anything for free as they have deliveries all over the area, so a consumer small order will be on the way to somewhere. Local nurseries will deliver pretty much most things for a fairly reasonable prices or free. And for those times that things just don’t fit into a car / suv or whatever I have, there is u-haul rental or HD truck. Needless to say that thought process went away pretty quickly 
that’s all internet being internet. For first time parents the list of “necessities” that you always need to have with you is about a mile long, and requires a suburban + roof storage box + possibly a trailer. It’s ridiculous what’s out there. Then people realize that that giant stroller that they bought is useless, the crap you need with you to go anywhere fits into a small bag, and you could have just as easily gotten away with a much smaller car.
