I have only recently (within a year so) gotten into Sthephen's books after reading IT, so last week, I put £10 (UK) into my bank and had a look on the play trade section of play (a UK based entertainment website - books, cd's dvd's etc) to see what I could pick up. I got Pet Semetary, Misery, The Shining, and The Stand: Complete and Uncut edition - for a total of £9.75. I prefer 2nd hand paperbacks - paperbacks because I generally read most in bed, lying on my side with my book in one hand, so they are easier and lighter to hold. 2nd hand, because a book is something you pretty much have no choice but to mark and damage with spine creases, and general wear, and I don't like to damage my newly bought things. Plus there is just something that feels cozy and nostalgic about an old book.
I hope I dont come across as cheap.
I think the word you want here is frugal, and there ain't nothin' wrong with watching where your hard earned cash is going! I myself like a good bargain when I find one.
