First, I love my Starbucks travel cup and I have used it for a 2-3 years. Now the oils from the coffee are causing the rubber(?) sip hole seal to rot. Now I find that a new top is not available from Starbucks. As the stainless steel should last practically forever, why can I NOT buy a new lid? I try to do my part to keep the land fills empty, so if anyone knows where to get a new top, please post.
