I think the Store locator on AMEX.com is not accurate. Even though it says the store sells it, most of the time the store do not have the cards, just the card board display box.
I was lucky to find 2 out of 5 stores in SoCal that had them. The other 3 stores, the employees didn't even know what they are. Last night I went to one of those stores to load my card, the 2 cashiers just gave me a blank stare. I told them,"swipe it, and the there will be onscreen instructions".
side note. I have been complaining about my new Citi Hilton Reserve. I had to call the fraud dept twice. I was able to get 1 charge in for $500 at Target, but after that got denied a few more times. I am still able to use the card to buy lunch, but now I have to call citi for a 3rd time. I guess once I am done with the required spend, I am done with this card.
