Why we like it

Biggest discount to date, anyone? The Lego Botanicals Peace Lily graced shelves earlier this year and was immediately one of our favorites. A peace lily that won’t poison your cat or droop is a gift that keeps on giving. Its 474 pieces build out to an array of lilies in three stages of bloom: two furled buds, two partially open, and two flowers in full bloom. It also includes a peach colored plant pot that doubles as floral decor that never dies. At $39.99, it’s down $10 for October Prime Day, marking its lowest price yet.

Why we like it

Lego’s Project Hail Mary building set got its first-ever discount for Prime Big Deal Days, knocking the $99.99 price tag down to just $69.99. Its 830 pieces build out to a replica of the Hail Mary ship, docked on a display stand. There’s a built-in crank that actually turns to simulate the ship’s centrifugal gravity system. Plus, there are mini Ryland Grace and Rocky figures to complete the build. Mashable Contributor Hannah Hoolihan pieced the set together and now considers it one of her favorites on her shelf.
