For some of the things I buy, I prefer just doing online, because it's often not easy to figure out where one particular thing is in the store. But when I have time, I do enjoy browsing in the store and discovering new things to buy that I never thought of before.

Home delivery in the U.S. is expensive because the labor cost is expensive, and because population is generally more spread out geographically. Cities in China and India have home delivery with much lower cost. But with the advance of robot technology, maybe not too far in future home delivery in U.S. could have lower cost too.
