Hello, I am new to the miles and points game and did a small app-o-rama in late November. I am getting organized to do a bigger one in a week or so, once 91 days have passed. I have been saving snail mail offers from airlines, hotels and banks , some of which have 12 or 16 digit "special invitation numbers." I have a few questions: 1) Am I more likely to get approved if I use the special number? Or should I follow a link, perhaps from a favorite blogger, so they get the credit, if I am as likely to be approved that way? 2) I saw a tweet from a miles and points blogger asking for a code for a particular card. ("Anyone have a code for a 100K AmEx Platinum?" Answer was: "are you 365 days since your last Plat? do you still need the link/code?") When I tweeted her, she said that the codes are not identified with a particular person - so that I could for example apply using a code my husband received. I at first thought she was referring to the 12 or 16 digit special invitation numbers I mention above. But was she referring to a promo code or URL, not the special invitation number? Can someone explain targeted offers, which may have specific invitation numbers, promo codes and/or URLs, in more than 140 characters?! I'd like to use whatever will make it most likely for me to get approved. Thanks!
