I ended up changing my mind on mugs AFTER I ordered this lid. Rather than return it, I thought I'd offer it here since I'd be losing out on the return shipping anyway & someone here can save a little money this way.

$18, includes free shipping CONUS. Paypal gift or buyer pays 3% fee.
(If you ordered it from the website, you'd end up paying S&H; I paid $3.60, not sure if that's different depending on location).

Lid will be shipped out asap from Maryland (buy it tonight, I'll ship tomorrow!).

DESCRIPTION FROM WEBSITE:
