Whether or not to tip for Lowes curbside pickup is ultimately a personal decision. While it is not mandatory, tipping can be a way to show appreciation for the employees' efforts and excellent service. If you feel that the staff went above and beyond to ensure a smooth and efficient curbside pickup experience, it may be appropriate to offer a small tip as a gesture of gratitude. However, if the service provided was satisfactory but did not particularly stand out, not tipping would generally be acceptable.
