If you want to make a Sag happy, introduce him or her to something new. If you want to make that Archer OTT blissful, give a gift that lets him/her introduce others to something new. As the "cultural ambassador" of the zodiac, Sagittarians would love a box of assorted chocolates — it'd let them share with friends, offering up random sweets they might not have tried before. (And collectively bond over how universally hated those strawberry creme-filled ones are, of course.)
