There is a Groupon deal for the next day for $50 off at least a $100 custom bag from Timbuk2.
You must use the groupon by Jun 30, 2011 and there is a limit of 1 per person available only only and valid only for custom bags.
Limit 1 per person, may buy 1 additional as a gift. Online only. Tax and shipping not included.
I don’t own a Timbuk2 bag but have seen them in person and they are very good quality and very sturdy.
