My name is malarkey and I'm becoming an ebook (and audiobook) buying addict! The vast majority of my calibre library is, fortunately, public domain novels, stories, essays, poems and the likes which I've obtained from various websites such as this one and Gutenberg -- in 2012, however, I purchased sixty-four ebooks.
Judging by the TBR lists of others in this thread (yes, I've read the entire thing!), my measly sixty-four books are child's play. At $704.80 for the year, I spent an average of $11.01 per book. However, an addiction becomes a problem when satisfying that addiction isn't within your means -- and I'm a part-time employed university student with three other rather expensive habits (tattoos, comic books, motorbikes).
I only read about twenty books per year, so even if I exclude my plethora of public domain works, I've managed to purchase enough reading material for three years in the span of one year -- and I've only read one of those books so far! My biggest issues are as follows: I don't wait for sales, rather buying things when I decide that they look interesting, regardless of the price (the Kobo emails are a killer); and I don't wait until I've read one book to buy another -- I accumulate books that I may not end up reading any time soon.
I simply don't read fast enough (or make enough money) to justify buying this many ebooks. I need this support thread!
