Dolphinluck, printing ourselves is probably the more practical thing to do. I had seen those labels, as well, but I would print clear labels if I can find some. Just haven't searched yet.
SuzyQ, the travel mugs you're thinking about are pretty colors and the $3.95 price is certainly reasonable enough. It's just that $50 imprint charge that gets me. Wouldn't be bad if I was ordering a lot, but just not practical ordering 12. - LOL - I think this is the first time that I've ever thought about being being practical.
