Thanks to a shipment in today of three styles of stainless steel straw water bottles by Nathan, it looks like we're up to twenty-one competitors in our upcoming BPA-Free Water Bottle Showdown. We're also still working on some SIGG news and analysis that is currently on simmer while we wait for some confirmations, elaborations, and inside information.

In the meantime, we'd like to let you know about a great giveaway that just fell into our lap.

We've been big fans of Thinksport insulated stainless steel water bottles [ZRecs Guide|website] since we first evaluated them last year on our now-laid-to-rest blog Gardenaut. We have also been on the lookout for a great giveaway to match up with our errant monthly newsletter, with which we've had an on-again, off-again relationship that would make Carrie Bradshaw blush. So when the head of Think Operations, the company behind both the Thinksport bottles and Thinkbaby bottles and sippy cups, offered to let us give away some, we were quick to respond.

Here's the deal: We'll give five Thinksport stainless steel water bottles to one winner when our September newsletter comes out on September 1. These bottles retail at around $18 for a 350 ml water bottle and $22 for a 750 ml bottle, and the winner can pick what combination of water bottles from Thinksport they'd like - all big, or two bigs and three littles for the kiddos, and so on - to share with their family, bestow upon their friends, or hoard for a near lifetime of water bottley goodness.

We haven't yet worked out exactly how this giveaway will work, except that it will in some way involve you actually opening your newsletter, and emailing us within a certain timeframe at a provided giveaway email address to let us know you'd really like them, after which we'll draw a winner at random. This arrangement is good because it gives you a distinct advantage over all those people who signed up for our newsletter two years ago, and have no idea who we are now, or have abandoned their hotmail account to the parched, pleading buzzards of internet spam, and it keeps us from woefully calling their names into the night, with no response, while you sit there wishing you'd won.

So! If you aren't signed up for our newsletter, we promise you'll like it; it's a monthly (or less!) roundup of our most compelling research, product reviews, and navel-gazing. You can sign up to receive it, and have a chance to win more water bottles than you could possibly need, here.
