Microsoft has started teasing Friday's "12 Days of Deals" promotion that will offer a Jawbone Mini Jambox Bluetooth speaker for just $69.99 both online and in-store, with an even lower price of $49.99 for folks who are first in line to get the speaker at their local Microsoft Store location.

Normally, the small Jawbone Mini Jambox is priced at $129.99, so Friday will offer holiday shoppers a $60 savings on the speaker, or $80 off if they are one of the first 50 people at a brick-and-mortar Microsoft Store, or one of the first 25 people at one of its smaller specialty stores. As with all of Microsoft's 12 Days of Deals offers, this one-day price cut is just for US and Canada residents only
