Regular priced Chloés in the US are a tad more expensive than regular priced Chloés specially since you get your VAT back if you purchase over 175 Euros from the same store on the same day. Easily doable with just 1 Chloé bag. If you bought them at Printemps and Galeries Lafayette you'd still get 10% off by presenting your passport (if you live outside of EU).
But, if you were to compare prices to when NM, BG, Saks, Bloomies, Aloha Rag and Chloé Bahrain go on sale, we have better deals here than there. When I was in Paris in July 2006, it was the height of Les Soldes and yet, none of the Paddies or the bags that I really wanted from Chloé were on sale at Printemps and Galeries Lafayette. You'll get luckier to find them, some 50% off discounts at smaller stores that carry designer brands.
If you're planning to get your VAT refunded, make sure to have all the paperwork filled up and signed before your departure. Make sure the merchant fills it up properly, stamps it if necessary. I've witnessed many a meltdown at Charles de Gaulle customs windows when American tourists realise their forms were not properly completed by the stores and the customs rep just won't budge to help (not that he can do anything anyway, it' wasn't his fault).
Good luck and enjoy your trip!
