Hmm. The discussion a few days ago on Spenda and Diet Rite was very heated and very enjoyable. I don't think people meant to sound snide and curt and perhaps this format is to blame. Of course it also brings us joy like Thi N.'s review, so perhaps things are best left at reviews and not opines.
I looked into the Diet Rite thing, they have a website as one hound pointed out. To call them direct 1800-696-5891. It turns out Diet Rite was this country's first diet cola, no caffeine blah blah blah, a few years ago they switched from asparatame to Spenda. Now they have flavors such as black cherry, tangerine, white grabe, kiwi strawberry. They are not all available in LA, but seems Ralphs and Albertsons carry the most flavors, Savon also carries the regular cola.
When I called to find where to buy Diet Rite in LA they were very helpful and promised to mail me a coupon for a free 12 pack. I love free stuff.
