99楼的引文出自博客 https://www.mashupmom.com
这个博客作者就是这本书complete idiot 's guide to couponing的作者 Rachel Singer Gordon
把transaction和shopping trip联系起来的就只有Rachel Singer Gordon这一个人
这个人是干嘛的呢？这是她自己的介绍，现在是主妇，以前是图书馆管理员
I’m a former librarian, but since Mashup Mom launched in 2009 I have been mashing up a career as a writer, blogger — and mom to two boys! I’m all about frugal living and healthy eating on a budget, and love sharing recipes, meal planning advice, book reviews, and frugal living tips. Stick around for plenty more about my family, cats, struggles with healthy eating, and… our backyard chickens and beehives.
后面附上的是这个人出版的书单，大部分是关于图书管理的，没看到零售或者法律方面的内容
给出这个说法的Rachel Singer Gordon仅仅是个家庭主妇，coupon这本书就是一个主妇教别人如何收集使用coupon，包括19章，都是归纳她自己博客的内容。
同样介绍怎么玩coupon的书籍在亚马逊上超过千本，这本书和其他各种coupon相关的主妇读物没有不同。"专门解释了coupon的所有名词”，这个是瞎扯，书里没有这些内容。我不知道你哪里得来“被所有coupon 商家借鉴”，“coupon届的经典"这种结论，正经的商家不会去借鉴这种主妇读物的。
