Is there a set of dale carnegie books that i can buy together?

like "how to win friends and influence people," "how to stop worrying and start living", "the leader in you", and a few others...is there any way i could buy all of them as a set like sometimes i see like the harry potter books sold as a whole box set. is there something like that for these books? if so where could i get the set? if not, how could i go to like barnes and noble or something and get them without looking like a loser in front of the other people and employees...i just know theyll be laughing at me on the inside, i mean, im still in high school so it would look weird if i got those books
