My big Amex Offers screw up with Tweet Deck and Lowe’s giftcards

Last week there was an awesome new Amex Offer for a $10 statement credit if you spend $50 at Lowe’s (deal is now dead). The reason this offer was so valuable is you can buy lots of different types of giftcards at Lowe’s, and essentially receive them 20% off in the end.

If you’re unfamiliar with Amex Offers, my go-to reference post is Frequent Miler’s Creating an Amex Machine. Turns out my own Amex Machine was not a well-functioning one.

I hadn’t seen a good Amex Offer in awhile, so I suppose I was out of practice, but here’s how a two-second error cost me quite a bit of time and caused me to miss out on $110.
