Although I’m slightly less obsessive that previously now I’ve found you can buy this reasonably reliably at Target stores, it still isn’t generally available anywhere – convenience stores like 711 and Wawa, gas stations, supermarkets, soda and beverage distributors.
Having said that, Target is running a great deal right now (I don’t know how long it will last) of 10 for $10 plus you get a $5 Target gift card. That makes the effective price $0.50/bottle which is unbelievable. I’ve cleaned out my local Target, you should do the same if you like this stuff.
Quick update as of Nov 27: It’s still as rare as hens teeth but right now it’s 99 cents/bottle at participating 7-11’s! I’ve now bought enough to last me through February. I’m not posting any more on this thread as it’s run out of steam.
