Cup goes on sale now; free coffee Nov. 7.

You gotta love a deal that starts this year and is good through the end of next.

And if that deal involves free coffee, all the better.

Bruegger's Bagels is releasing its 2014 Bottomless Mug now, which means that if you buy a mug for $169 you can get free refills for the rest of 2013 — that's 62 additional days, folks, of free joe.

OK, so $169 may seem a bit steep, but the money goes to a good cause. Proceeds benefit Children's Miracle Network Hospitals.

Bruegger's launched the bottomless mug program 11 years ago and started designating part of the proceeds to Children's Miracle Network Hospitals in 2010.

You can get a mug now or wait until Nov. 7, when Bruegger's hosts its annual free coffee day. On that day, you can get a free cup of coffee for the asking; they are hoping you will return the generosity with a donation of spare change or spare bills for the Children's Miracle Network.

Last year, customers kicked in more than $25,000 during free coffee day at all of Bruegger's 275 bakeries. The deal is good from opening to 2 p.m. Nov. 7.

Bruegger's has several Tucson locations including at 1064 N. Campbell Ave., 88 W. River Road and 1 W. Congress St.
