My fav are frozen thin mints and the samoan ones! Oh and the peanut butter ones! (tagalongs?) I don't have anyone in particular I buy them from. Usually Mom gets some. The poor girls have been outside walmart faithfully the past few weeks though. I do want some, I just always forget on the way out!
My DH and I were at Lowe's a few weeks back and there was a girl scout selling cookies. We hadn't eaten dinner yet and walked out with 8 boxes, 3 of them Thin Mints.
