It is getting warm here in California and I was thinking it might be time to look at Iced drinks!
Amazon does have several varieties of Iced Tea available in K-cups:
Green Mountain Southern Sweet Perfect Tea $14.88 for 22 (so .67 per cup)
Green Mountain Variety Pack of Iced Tea $14.88 for 22 (so .67 per cup)
Green Mountain Half and Half Perfect Iced Tea $14.88 for 22 (so .67 per cup)
Green Mountain Sweet Peach Perfect Iced Tea $14.88 for 24 (so .62 per cup)
You can see more Keurig Iced Tea K-Cups varieties here. These all have free shipping with AmazonMom/Prime or with a $25 order.
Has anyone tried these yet?

I have the lemon, raspberry, and sweet berry lime. They are all really good!! My favorite is the lemon! I drink it almost every day:) The sweet berry lime tea is good, but has more if a juice taste than a tea. Hope that helps!
