I clipped this image from a Lowes email blast I received this morning. Trade in any competitor’s rotary hammer, and receive a 20%-off instant coupon towards a new Bosch rotary hammer.
The deal is only valid in-store at your local Lowes, and expires on 10/31/13.
The wording of competitor’s rotary hammer might have some wiggle room, but might be up to the discretion of the staff at your store. I would think that you should head over to the contractor desk rather than customer service, or maybe even call the store first to confirm your store is participating in the promo.
I could find no fine print that mentions whether the discount is only valid on corded and not cordless hammers. If they don’t have your preferred model in-stock, but do offer it online, they might be able to order it for you.
