Very true, but I've also noticed that because of all the internet business that's going on now, I see more small businesses becoming authorized FEDEX and UPS shipping stations.
While this may not be true for bigger heavier items, slapping a prepaid shipping label on the box and dropping it off on my way to do other errands is just as easy, sometimes easier than returning to the store. YMMV, but as a member of this younger generation I see fewer reasons to go to the store every time I need to shop. No hustle and bustle, no getting there and them be out of stock, stuff like that.
If tax laws change than other considerations need to be made. Like when NY instituted their Amazon tax law. That seriously curbed my amazon purchases. I still buy a ton of crap from Amazon, but I knew look elsewhere first and only default to amazon if I can't find it or if the other place's shipping timeframe doesn't fit when I need the item by (I still maintain my prime membership).
So if the tax laws change, then maybe I'll start lugging myself to stores, but I still don't see B&M stores being able to keep up with internet direct in terms of everyday pricing. Without a physical structure to maintain as the interface between retailer and customer operating costs are much lower. Yes sometimes it's helpful to get personal attention, or in your case have someone to yell at face to face when something goes awry, but online chats suffice for my purposes
