@petolino this doesn’t help you location-wise, but maybe it will give you some comfort that they haven’t gone out of business - I picked up your chili paste in Chinatown nyc. I imagine a few bottles would fit into a a fixed-rate USPS parcel… 
It was not by the massive display of LKK and Laoganma pastes, but in another aisle near the non-chinese (korean, japanese) condiments. I would have missed it if I hadn’t specifically been looking for it.
Having tasted it, it seems halfway between the ubiquitous chili garlic pastes and this broad bean chili paste - I recall seeing a broad bean garlic chili paste too when I picked up this one, it might be closer.
Also found this sesame paste by Lan Chi - labeled Salad dressing.
