I have to agree - there’s good and bad. Amazon has been an enormous help to us during Covid, and even before.
We’ve bought hundreds of books, for instance, and Amazon always shows you used booksellers from whom you can buy for much less.
Most of the ‘used’ books I’ve bought that way have been in pristine condition - and I’ve supported small businesses at the same time.
(I’ve been trying of late to buy nothing from China, though.)
