Girl Scouts uses 2 bakers for cookies Little Brownie Bakers and ABC bakers. Depending on which bakery your local council has contracted with will determine your type of cookies. For example, Little Brownie has Do Si Dos, and ABC has caramel delights kinda the same cookie but different names. The only thing in common is both bakeries is that they use the named Thin Mints for that cookie.
Edited to say that both now used the name Girl Scout Smore for the new cookie, however the cookies are different. Don't even get me started on that one.
