The black 29 inch is selling for $124.35 you also need to add the 21 inch to your cart for the free offer to take affect.
They also have a deal for 10% off all home online when using code thanks along with max members getting an additional $15.00 in points back for a purchase over $100.
This brings total to around $112 and you can get free shipping or pick up in store. They list original prices as $440 for 29 inch and $320 for 21 inch.
These suitcases are incredibly light and well built suitcases. I already use the 25 inch and a 21 inch and am replacing some older luggage.
