When there is the free tool battery promotion. Add them both.
They can't just mark one to zero. So they calculate the price of it and reduce it by % from each item. Why the receipt always says max refund value. That's max refund value returned by itself.
So basically you get a chunk off the tool. Just return the batteries. Has to be a promo going on which is all the time.
Here you can see the battery/charger pack is $200. Router is $200. Add them to the cart and you see the discount. Each was marked down to $99 each.
Return the batteries, get $99 back. The tool stays $99. You just got the router for $99.
If you don't want to deal with the whole return thing, you can even order what you want from the store, then order what you don't want to be shipped. Go pick up the part of the order you want at the store, then cancel the order for the other half. What you picked up stays the same price. You can even order both to pick up from the store, then immediately return the half you don't want during the pick up.
Sometimes you can stack this promo with a buy more save more promo + veteran/MIL discount if the cashier person is cool and wants to flex their know how.
It's how there so many sellers on Facebook Marketplace. They buy these bundles, split them up and sell everything separately. Most people don't know you can do this. So if they see a $100 battery for $90 no tax on FB, they think it's a good deal. When the flipper got it for $50. Sometimes you can catch stuff on clearance. If you dig hard enough some stores will have a surplus and clearance out the same items, so you can get it for less just by punching in that zip code.
