For those who are looking to purchase Tumi luggage/bags, Nordstrom has Tumi luggage, backpacks and other products on sale for 20% to up to 40% off today until September 24th.
Apparently, Amazon has some of the luggage on sale for up to 45% off. A few samples:
ETA: For those who'd like to combine with cash back from those certain cash back sites, Ebags also has Tumi on sale for 20% off across the board. For example, TCB has 16% CB on ebags right now, which effectively makes it 36% across the board. This may be a better option if the item is only 20% off on Nordstrom.
