Lens-Shaped Coffee Mug for $10 [was $11]

And now to a lens of a different kind, a novelty gift with some semi-practical use, Groupon is offering this lens-shaped coffee mug for $10 (was $11) each, with a limit of five per customer. Free shipping with orders of $34.99 so you may want to add it to a future order if not planning to buy anything else now. Shipping is $4 for sub-$35 orders. The specs say this is 12oz but keep in mind, in general, most of the coffee cup listed measurements are usually fully full (which no one uses that way because you get spills all over).

Also of interest if you have any Groupon store credit or coupons or gift cards.
