When both items were cancelled due to incorrect inventories I cant help but believe that the Internet retailer, or their supplier, is either (1) playing games, or (2) doesnt really have control of their business.
In any event, charging me at time of ordering, holding my funds for three weeks, before advising of a cannot ship position, is completely contrary to the reputation Nordstrom has sought to develop and maintain.
Perhaps you should consider charging at shipment, instead of order for Tumi items only (if theyre at fault) or for all items if its Nordstrom that has inventory management issues.
