You can get 2032’s on Amazon, fairly cheap.
yes I was impatient and didn’t think it’d be $8 for 2 at HD, was willing to pay extra to pick up as HD is just 1 mile away.
Next time…
The Sony 2032 are very good for the money —most of the time no more than a $1 a piece
Prime Membership Giveaway: Ends 2/24/20 @ 4pm CT
If you are not a Prime member then you can enter for a chance to win 1 of 20
one year Prime memberships.
No purchase required,only a post in the thread on Amazon owned Woot.
Read the rules.
As usual give the good deals to new customers —- the loyal prime members don’t qualify
But to get in on Prime deals you must be a member.
It's a common practice by many companies to offer something for a new signup.
Amazon used to have special Prime membership pricing on Prime Day but I have not seen it in a while.
I cancelled my membership on Prime Day and then joined with the lower price.
unfortunately mine is payed up for 9 more months —- things like years of loyalty means nothing to these companies anymore — my first year of prime was $69.99 —I can’t remember how long ago that was
I’m piggybacked on my wife’s account. 2 for the price of 1. 
amazon and aliexpress both have CR2032s under $.10 each, though you may have to buy 20 of them
at least the shelf life is long
most button batteries and coin cells can be bought for under $.20 this way
some alkalines like LR44 can be under $.08
Every other year I order 5 or 10 packs of all the common lithium button cells from Aliexpress, and they cost $2 or less. Sometimes the batteries run 70% as long as the brand names, but I get 10 for the price that I would pay for one locally. For some devices if the batteries are hard to replace, I pay extra and order Energizer or Duracell from Amazon.

Trustfire 700 lumen mag ring dive light $10 was $30. 26650 not included.
Well, what the heck…looks nice and stout
Thanks for the heads up. I just ordered one.
Just fyi on the DF008, KD had it here for $30: http://kaidomain.com/S024233-TrustFire-DF008-Cree-XM-L2-700-Lumens-3-Mode-LED-Diving-Flashlight-with-Holster-Black,
and on Ali for $23 here: https://www.aliexpress.com/item/32790377769.html?spm=2114.12057483.0.0.27e31c02bBNPlO
It's been listed since 2017 at best, rated at 700 lumens, and it's driven at 2.4 amps, as the KD listing says. No way can it do 700m (meters) like the Amazon listing says - Ali store says 200-300 meters.
For $10, probably still a good deal. Maybe that wrist holder is worth the $10 alone. Reviewer on Ali says it requires long (protected) 26650.
They must have confused 700lm with 700m. 
One of the images in that Amazon listing shows 300m range.
But the pic says 7500 cd, which is like 173 meters. 7.5 kcd sounds too low for that light anyway. 250-300 meters sounds about right.
The specs are a mess - who knows... But 700 meters as the description says is wayyy too high.
Dang I have one Thrunite protected but others are flat tops.
Also it appears to start with strobe but for $10 I couldn’t resist.
“Currently unavailable”… whew! 
Probably would’ve bought a bunch even though I really don’t need any more lights.
After I did some research, decided against it. They probably had only bout 3-5 of them, I'm guessing.
