I'm largely interested in used/refurbished items, I don't usually have a thousand to blow on hobby music gear & would prefer store curbside pickup (packages in San Francisco get stolen within seconds of arriving).
For online, ship to store/pickup in store is super important to me (and probably many others). I'm not sure why more places don't offer it.
This also being said, I don't believe I've ever found GC/MF in person to be useful or any better than Amazon. No one working there was actually knowledgeable about their lines of products or about instruments in general, they just kept harassing me over buying worthless GC-offered third party warranties that they refuse to pay out and covers nothing
