Nordstrom is fine to purchase from, but you may want to try http://www.strawberrynet.com as well. The term "Habit de Fete" refers to the gold refillable canisters that a bottle of Jicky EDT or PDT would fit into.
I would never recommend someone by a new bottle of frag from eBay, but if you try the womans fragrances and choose used fragrances you can be assured of a little more safety and may find a decent buy. You may have to keep checking eBay for a while to find what your looking for, but it could be worth it! Oh, and check Amazon.com too!
