Forsa is not a surplus-bag app.
The best-known model in this category sells you a sealed bag of whatever was left. We deliberately built something else, and the difference is the whole product.
The surplus-bag model pioneered internationally by Too Good To Go proved something important: people will happily buy food that would otherwise be discarded, and merchants will happily sell it. That was not obvious a decade ago, and the category exists because somebody demonstrated it at scale.
It also comes with a defining constraint. In a mystery-bag marketplace you commit before you know what you are getting, collection windows are narrow, and the offer only exists on days a merchant happens to have a surplus. That works as an occasional treat. It struggles as a way to decide dinner.
A marketplace you can only use on the days your local bakery over-baked is not a marketplace you build a habit around.
Forsa starts from the opposite end. Full-menu savings mean every item at a partner restaurant is at least 10% below the counter price, all day, whether or not anything went unsold. Happy hours add timed depth. Merchant deals add invention. Surplus is the fourth mechanic, not the only one.
The practical result is that you always know what you are buying, you can have it delivered instead of collecting it, and the app is worth opening on an ordinary Tuesday. Surplus is the part of Forsa with the best story. It is not the part that makes it useful every day.
