Thrift shops are the bomb when it comes to buying paperback books. Where else can you get good entertainment for hours for only a buck?
Of course a library is much cheaper, but considering l do finish my books when l'm on the road, the last thing l want to do it lug a library book around. Thrift shops are the next best thing. If l forget the book somewhere (in my hotel after check out, or on the plane) it's no major loss.
The only other place for cheap read is Chapters/Barnes & Noble or any of those chains that have those super comfortable chairs that you can sit in and read for an hour or two. I just did that on Sunday. A book that l have been meaning to grab, actually grabbed my attention when l popped in to the book store on Sunday. 'Wheat Belly', pretty interesting/compelling stuff. Once l am in my van travelling with a kitchen and a fridge, l plan on cutting out the wheat in my diet.
