I just found this thread from here:

I don't even know how many ebooks I have, I haven't actually counted. I get a lot of freebies. Actually, the Sony book store has a lot, and it's more easily searchable than Kobo's. Most of my books are in my Sony Library on my laptop, as well as on my eReaders, but I've also downloaded directly to my Vox from my Mantano (sp?) app. If it's a book I know I'm only going to read once and if I can do so within 2 weeks, I check my library first and download it to Overdrive.
I try to use Kobo's discount coupons, but they can't be used on many of the books I want, so I have bitten the bullet and paid full price. This weekend, when doing that I decided I would set a $20/month limit on my ebook buying. We'll see how that goes.
