Buying on eBay always involves a degree of risk. It depends on whether or not you want to take the risk.

I shop locally (I like to see and check out the stuff first), and we have a local luggage shop who will discount Tumi for regular customers. Been serving our little neighborhood for many years.

By the way, he is extremely (and brutally) honest. If you want to pay for the Tumi name, he'll gladly accomodate you, but he finds it not worth the premium price, considering the way the airlines treat luggage these days. He can recommend similar quality for almost half the price. Never steered me wrong!

Shop your local businesses - you may be surprised by the results!
