Many many times I've consciously thought "I'm going to give retail a chance!" and go out of my way to find something at a physical store. Often it's because I might want it that day; sometimes I've just wanted to explore.
Yet I always end up wasting many hours. I can't drive, so it's public transport and walking everywhere for me (that's fine, it just adds to the time). My experience has been that if you know exactly what you want and it's anything slightly off the beaten path, you're going to have a hard time finding a store that will stock it.
Recent examples that come to mind: a certain kind of USB cable, an SSD, musician's earplugs, an induction cooker. Plus almost any book that I want.
This year was the first year that I've done the majority of my Christmas shopping online (I actually managed to get to it early enough!). It's been hands-down the best experience I've had Christmas shopping. Not to mention that I haven't had that Mariah Carey Christmas song shoved down my ears this year as a result :)
Physical stores just can't compete for certain kinds of shoppers.
Also, I hear so much about physical stores treating their employees like shit. Primary examples include GameStop and EB Games. When I think of that, I think that some stores deserve to fail.
