Update: Sorry guys it looks like these are already gone!
If you are on the hunt for a BPA free stainless steel bottle at a good price, here is one for you. This Evergreen 27 oz bottle is only $4.99 (org $14.99). Cheap enough to pick up a few. They come in green and white and they seem to be comparable to the Klean bottles which run around $15. And they ship free with Amazon Prime. You can head over here to check it out. Saves money on bottled water too.
