I just ordered RN Notes to have on hand for my clinicals starting this Fall.
It was recommended by my clinical instructor. She said she doesn't make a habit of recommending books to students but felt this would be a really good investment for us even after we graduate.
Barne's and Noble had it on sale last week. I ordered mine last Thursday. It was $15 and some odd cents and if you had an order of $25.00 or more you got free shipping.
Some students in my drug calc. class looked around on the internet and said that B&N had it the cheapest, but only if you ordered it online. It was not on sale in the store. They said Amazon
, eCampus.com, etc. were selling it anywhere from $21.00 up to $30.00.
