Upgrades are those little extras that help improve your lemonade stand, such as cash registers, fridges, stereo systems, or signs. Upgrades can help attract more customers to your stand, help them wait longer in line, speed up your service time, or improve your storage capacity, among others.
Some stands have certain basic upgrades built in and included in the purchase cost.

Click the Upgrades button to open the Upgrades display. Click the arrows to review the list of upgrades. Only the upgrades that are available for your current stand are shown. Each upgrade has a cost and type.
When you’re ready to buy an upgrade, click Buy this Upgrade.
