On a national professional musician's forum there has been a discussion about the loss of local shops where you can audition the gear you want or need.
Here's a great quote that sound exactly like what we talk about here all the time:
We have spoken with our wallets, and said "this is what we want". Back in the 90's, ma & pa places were getting killed by mail order retailers. Tons of people came in, checked out what they wanted & then saved $50 bucks by ordering it mail order... from places like GC & Sam Ash. Now that GC & Sam Ash have spread throughout the country, they've fallen victim to the same method... people check out their toys & trucks & then order it online from the best price giver.
When you shop for price, there will always be someone to offer a better deal... as long as you don't care about being able to look at the product, touch it, & talk to someone that can explain it. If a business wants to have skilled pros that know product & know how to sell, they'll have to be able to pay them. If a business determines that most of the market wants it cheap, they'll get cheap help & let the product sell itself.
