$15 Neck Knife
Dorcy.com is having one of their occasional “buy one get one free” sales. I’ve found Dorcy’s support folks quite reliable, and for alkaline or NiMH powered lights, for friends and gifting, their products are decent.
Buy one get one free with coupon: BOGO
*Requires coupon code and two of the same items added to the cart (multiples of two). For a limited time only and while supplies last. Expires 8/22/2020.
EDIT — it’s actually “order two pay for one” and the checkout page really confused an elderly neighbor,.
If you pass this on to someone, make sure they understand
— they have to put “two of the same item added to the cart” and
— enter the BOGO code, and
— applythe code,
then it shows the credit amount being subtracted from the total.
Then look carefully to select the “free shipping” option otherwise it hits you with a default pricey shipping charge.
