So some good news and some bad news. First the bad, I called Amex to discuss my frustration with losing the 100k offer and after being bounced around a few places all I got was the usual wow, that's a good offer, I wish I could pull that up (I'm serious, that was the reply when calling the new application and the existing cardholder lines). To be fair, the existing cardholder rep was very professional and tried a bunch of things for me, but no go. As expected there was nothing they could do, so I did have them lodge a formal complaint on my disappointment with their random offer changes. Don't expect it to go anywhere but I was pretty frustrated at that point.
The good news. So I did some searching and found a DoC post about what happens when you make some typos in your name/address on the amex prequalified offer site (on the amex website, not cardmatch) and after some trying I was able to get the offer for DH. So I quickly applied (just did a quick screenshot of the terms) and he was approved. But of course I have no idea where the card is going because of the typo that involved entering a previous address (I did use the correct address on the actual application though). DH did get the confirmation email and we even have the virtual card number, but I've read reports that even though I corrected the address on the application it will still be sent to the old address. So I'll have DH call later and see if he can get that corrected (along with the typo in his name, darn browsers and their form prefills...).
For those interested, I used the process in this
comment.
@miztressuz, here's exactly what I did when I got the offer (then lost it) from cardmatch. Went to cardmatch website (Chrome browser on my iphone), entered in my accurate information and that pretty 100k offer was right at the top. I clicked the orange Apply button and was taken to an amex application site. I opened the terms in a separate browser window and did a quick save. Came over here to post my original question (I use a seperate mobile browser for this site so I didn't navigate away from the applicaiton) and then went back to browser to apply. By that time (it wasn't more than 10-15 min) the application link had expired. I tried a bunch to get it to come back up using cardmatch but nada.
