Valid through tomorrow (10/17/2014):
American Airlines is offering increased portal rewards for select merchants via their AAdvantage eShopping Portal. Horchow 10X, Groupon 9X, etc.
If you want to shop Neiman Marcus, consider first buying a gift card from Horchow via this portal offer. Horchow gift cards can be used at Horchow, NeimanMarcus.com, Horchow Finale stores (Dallas area), or Neiman Marcus stores. And, I recently found that buying Horchow gift card (both e-gift cards and physical gift cards) do result in earning portal points. Of course, once you have the gift card, you can then go through a portal again to Neiman Marcus to buy merchandise and earn even more miles.
When considering buying or using gift cards via online portals, don’t forget to check the Frequent Miler Laboratory to see what works and what doesn’t. Terms & Conditions listed on the portal site itself is rarely the final (or correct) word.
