Very easy shops to do. I typically pick them up as fillers, if I have to waste some time between assignments (like banks that are close together but I need to wait 30 minutes or so), or if I have a long day and know that I need to force myself to take a break (might as well get paid for it!). If it's the same bookstore that I'm thinking of they typically sell "classics" at about that price point. As I have a teenager who has needed these exact same books for school, it has saved me $$ which rarely happens. I have had her give me a list of her reading list and I take several to fill it (as a matter of fact, Pygmalion and Romeo and Juliet are on the shopping list for this week). With the multitude of numerous expenses that have hit for her school this year, any opportunity that I have to defray them is much appreciated!
