So I noticed today that comixology has a Supergirl sale going on right now and I thought I'd check and see if there are any worthwhile volumes or issues to get. I'm a complete beginner to Supergirl (and the DC universe as a whole), and basically know nothing about her except that she exists and was in a few episodes of Smallville. Are there any high quality story arcs in the sale? A good place for a beginner to check out the series?
Here is a link to the titles on sale:

Thanks!
