What are you doing with the membership that is making it so sticky to not move elsewhere?

Buying things online? Have you tried purchasing from anywhere else? The level of convenience is night and day.

Can't say for USA, but in EU if I want something I can find at least 5 online non-Amazon stores that sell it. Often times they are also cheaper. I refuse to buy anything on Amazon anyway, don't even have an account and I can still get my stuff.

B&H is good for what they carry, and has two day shipping.

As someone who avoids purchasing anything from Amazon like the plague - B&H is great alternative. I have a set of "shops" that I rotate through depending on the product type:

Electronics - B&H

Computers - Microcenter

Musical Gear - Sweetwater (even though they got bought out by private equity, my sales agent always tries his best to do right by me)

As others have said, nothing for me has come close when it comes to reliability, variety, shipping times and ease of use.
