Biggest single item purchase was buying the Embassy Pro from Start9 right at release, aka in the middle of the bear market, which costed over 8.89 million sats. Probably only need less than half of that if I were to buy it now, but at least I got a dope box hand drawn by MADEX.
Most coin spent on a single vendor, but over multiple orders is Coinkite. I have no self control when it comes to Coinkite hardware. Probably blew over 12 million sats on them over the past few years.
I need to guard my stack better and put some control on the impulse buying...
