Uncollected Bananas auto-collect for half the amount.
~ BTD6 descprion
Banana Salvage is the second upgrade of Path 3 for the Banana Farm in BTD6. It allows outdated bananas to be autocollected at half their original value. It doesn't help much when compared to the Marketplace upgrade, but it helps when trying to spam in higher Banana Farms without Banana Farmers or with terrible micro, as the Marketplace upgrade limits purchase of Banana Plantation or its subsequent upgrades. It costs $170 on Easy, $200 on Medium, $215 on Hard, and $240 on Impoppable.
