Aren't they $129 at homedepot.com? Are there still $20 off $100 Northern codes that are valid? That's approach #1.
I was wrong, $139 ea:

Approach #2 is buy HD gift cards at giftcardzen for 10% off, you just saved $14 right there. Then try the Northern thing or just a Lowe's 10%, now you're down around 20% net discount and close to $100 per battery which I consider good for a
new M28.
I watched ebay for awhile myself, finally gave up as it seemed every real M28 got bid up $130+. I really don't think most ebay sellers will keep your warranty intact unless it's like toolup or toolbarn selling on ebay. But I don't know that for a fact.
I got my last 2 through Zoro on a sale for around $100 ea, I was satisfied. They were still 18 months old. I don't think Zoro/Grainger is turning these things over much obviously (but ebay is as every new one put up sees action IME).
If there are any used batteries on ebay at $60 ea they're decent but it's a **** shoot - might last 2 months, might last 3 years. Here ya go, these guys are legit

I've had good luck w the used batteries but one died after a year or so. You just have to decide if the reduced cost is worth the gamble
to you. And it's worth noting if you're powering the bandsaw batteries in top condition are never a bad idea, IMO the bandsaw is the highest-draw tool in the line-up. That said, I used mine extensively with used batteries purchased on ebay and old 2 3/8" oil field pipe. Like most lithium-ion, they either take a charge and work fine or they simply
don't.
edit: and where's sberry with the blood warmer battery review? Did he ever receive that? That was a potential line for all GJ members to get cheaper M28 batteries, if the OP (of that thread) is still willing to source and ship them.
