Before checkout

What should you check now?

Confirm the size, color, seller, shipping and current total on Amazon before buying.

For Tools & Home Improvement, also confirm on the listing:

Tool-only vs. kit: whether batteries and a charger are included in this price.
Battery platform and voltage, if you already own tools from this brand.
Who honors the warranty, and the return window for the seller shown at checkout.

Amazon’s checkout total—not this page—is the current source of truth.
