Like goods bought before they hit the shelves

PREORDERED

Securing a new release before its official launch might involve this action.

This clue describes items purchased in advance of their official release date. "Preordered" fits because it combines "pre-" (meaning before) with "ordered," matching the idea of buying goods before they’re available in stores. The phrasing plays on the literal meaning of shopping early, with no hidden wordplay or tricks.
