Product Drops is the latest feature to be tested by microblogging site Twitter. The new feature will preview upcoming product releases from different merchants, and allows brands to showcase items prior to going on sale. Users can also sign up for in-app notifications to be reminded before the release.

"With Product Drops, when a merchant Tweets about an upcoming launch, you will see a 'Remind me' button at the bottom of the Tweet," the company said in a blogpost. With one tap, users can request to be reminded of the Drop.
