The amount of research that needs to be done to purchase even the most basic stuff online is beyond paralyzing. I hate shopping irl but I think I hate online shopping even more.
This is how places like Costco can be worthwhile even if they aren't technically the best possible deal - I trust that if I buy something there I won't be terribly disappointed or overtly screwed over even if I end up paying a bit more than I absolutely had to.
Costco is the hero we need.
