If I recall, most libraries subscribe to a digital service called Hoopla, where you can read the Buffy Comics for free. You can also get Sandman for free, which is a better read. I mean, do you really intend to reread the Buffy comics? Most of them just aren't that good. You can also find Omnibuses for sale at Ollie's, along with a lot of other comic books, and a large variety of Bibles. It's a very odd store.
