I bought 4 of them, over 3 transactions, on one account. I used the coupon codes that were on their main page. (USAS35, for $35 off $219, and so on)Total with taxes and fees for $921.02. (this number total is charged to credit card). I'm not sure how the -15$ off works through paypal, but I used it with my Citi 2% cash back card. I also had the urlhasbeenblocked-app open which has a 20% payback. That should be another $184 off my total. And another $18 off with my 2% card. At $921 I will have a 48v battery bank at 280ah. That's insane. Hopefully the other discounts work and I will get it all 4 for $720ish. Sorry for the jibberish... Hope this helps someone.

I have 3 of these on a bus to RV conversion that we mostly run in the winter. I was concerned about temps and being able to operate them in cold weather, and so far so good. We went as low as -30 F this winter and when the diesel gelled I was able to use a heat gun run off the batteries to warm the fuel system back up, get additives into the fuel system, and get everything running again.
We had to replace one shortly after receiving it that had a finicky Bluetooth module and didn't like to connect. The replacement was super fast and easy.
I plan to pull our remaining AGM batteries out, they're not worth the weight and space when these work so well.

Edit- I bought mine through their ebay site.

This is not a premium brand, but they have been around for a while and reviews are generally good. I would say they sit somewhere in the mid tier as far as batteries go. The good thing is that they seem to be not a fly by night company that will be gone tomorrow if you have problems. Their customer service is definitely in China though.
They hit a sweet spot of bang for your buck. I'm not sure that I would trust them with my life, but for non critical use they are good.

you don't want to pay local taxes?

Of course not lol. But I'm used to seeing "Sales tax" as a line item, not "Additional charges" So that was throwing me off.

Thanks for pointing out the obvious.
