Never seen one.
If available, chances are it will be more expensive.
Have a link?

3.7V plugpacks are available. I think they were for some old phone. 3.7V may be within spec for some 3.3V devices, but I'd probably regulate 5V to 3.3V because 5V is far easier to find (also it allows you to use higher voltage plugpacks without causing much trouble.
