I’ve been cutting back on Amazon purchases during the pandemic since I know the workers are extra pressed to keep the essentials moving. I sometimes buy books from them, but my favorite source is Half Price Books (hpb.com). I miss going in to browse, but they do have an excellent online marketplace. I’ve placed some orders with them since the pandemic, and they’re excellent about promptly sending your stuff. The big tradeoff for using HPB instead of Amazon Prime is shipping — all orders have a $3.99 fee added. However, if you’re able to get several books ordered from the same branch of HPB, you can cut down on that cost. Hope that helps!
