Is the marketing technique described in this excerpt an example of Manipulation or Persuasion, and why?

Theme parks use a neat technique to sell souvenirs and gifts. Almost all their park rides exit into a nice little (or big) souvenir shop with nice display and affordable prices. It's a great feeling for you to impulsively purchase a small "relic" after having experienced a thrilling Indiana Jones ride! Your child may need to be the proud owner of some confiscated magical goods from Harry Potter's world. (Mehta, 2011, para. 4).
