Bookshop.org is what I use, generally. They have sent one damaged item in all of the books I've gotten from them and they were super nice and efficient in getting it replaced, plus they sent me a discount code for my next order (in addition t9 fixing everything for me for free). That was pretty early on in their existence, so not sure if its the same now, but overall, I've been quite happy with them...you can designate a local bookstore to get a part of the sale, but I don't think its necessary. You can also order from a local bookstore directly, but I'd talk to them first. I have one local one that has zero problem doing it and one that prefers customers use Bookshop, just because getting special orders in/having to sort and repack them/get them to the post office/mailed out is a lot of extra work for their limited space and staff...
