Amazon makes everything really easy, particularly wish lists, but not everything I would desire for a gift is sold on Amazon and frankly I don’t feel a need to send all of our money to Amazon. This page is a “list of lists” for places that I actively keep lists of gifts or items I would like.
For books I’m keeping that list on Bookshop.org. Bookshop is a great book store that is directly working with local book stores to keep them part of our communities.
For electronics and gear I have this list on B&H Photo Video. B&H has everything around cameras and AV gear.
And yes, like most people I do have a list on Amazon as well with some things there.
