I'v been drinking the diet Kirkland Green Tea with Citrus from Costco.
It does use aspartame. But it taste alittle sweet.
I like the diet Kirkland Green Tea with Citrus much better then the Lipton diet Green tea with Citrus.
I'v tasted some other drinks that use aspartame that taste way to sweet.
I'm hoping the diet Kirkland Green Tea with Citrus from Costco uses alittle aspartame
