Speaking of Target: If you need a good travel mug for your coffee, Target has the Contigo Extreme and Oxo Liqui-Seal, both in stainless steel, marked down from $20 to $17 this week. The Stainless Oxo is definitely vacuum insulated, it's gonna be a keeper I think. The Contigo may be foam insulated instead of vacuum- I'm testing it right now with hot water. If it turns out to be the foam version, back it goes. No Costco stores here so that's not a local option for the Contigo, I may have to order direct to get one of the good ones. Will know for sure in a few hours.
