I stepped back from the precipice last night. A book I wanted and that would apply to one of my annual challenges was available in hardcover for under a buck in the Amazon marketplace, so with shipping it would be less than $5. The ebook is $12.99 from PRH, so no hope of a discount there.
It was hard. But I knew if I gave in this early in my resolve not to buy any pbooks for six months, I was cooked. Whew! I know from experience that it gets easier as new habits are formed.
On other fronts, I have to admit to having bought two ebooks thus far. One's a $1.99 deal; the other a $2.99 deal for which I used some of my slow-shipping credit. I'm not worried, although acquiring at this rate will man an addition to the TBR by year's end, so I need to be mindful. Fortunately, we've all agreed that books which are free with the shopping credit don't count!
