Many of you seem to like the lens thermal coffee cup and we saw the following deal:

Nikon AF – S 24 – 70mm Lens Thermal Insulated Stainless Coffee Cup $19.76

This sale requires coupon code MAS1P and expires 05-18-2011.

Haven’t tried it myself so would be interested to hear from any who has one if it really keeps the coffee hot and for a long time.
