I ordered two tumblers w/ straw and only one of them included a straw. I emailed the customer service dept. (after hours) and they responded first thing the following morning, stating that they would ship out the straw immediately.
I rec'd the straw and an additional lid that can be used w/ the straw or for sipping (lid contains a rotating cover to keep from spilling when straw is not in use).
Thought it was a nice gesture - much appreciated.
I also own 64 oz. battle bottles, too. Great product
