Best Buy and American Express - $20 off a $200 Purchase

Best Buy, American Express and Twitter - $20 off a $200 Purchase

Update - Alive again but with tweet #AmexBestBuyOffer.  I have done this a few times and every time I add the money to my serve account.  I haven't spent much money outside of prepaid cards in a little while.  
Twitter allows pseduonyms so feel free to start multiple twitter accounts and sync one Amex card per account to get $14 for ever Amex card you have! 

In addition, this will work with your synced American Express on Facebook.  I don't know what happens when the same card is synced for both deals, but I assume you won't get the credit twice.
Edit: Dead - maximum number of people have signed up

Spend $200 at Best Buy with an American Express card and get a $20 credit!  This can mean more free money!  If you want more free money ;) make sure you get your $25 serve promotion.

Here's how to do it:

1. Sync your American Express card with your twitter account (no need to do it twice).
2. Tweet #AmexBestBuy20
3. Wait for your confirmation tweet from American Express that you will be getting the credit
4. Spend $200 at Best Buy (In store or online) and you will immediately get an email from American Express confirming the credit

-   Gift cards count for this!  I bought two $200 Best Buy Visa gift cards (I have two twitter accounts).  Each has a $6 activation fee and I got my confirmation email.  I ended up spending $186 for $200 for each of the visa gift cards for a return of 7% on each card or $14 for free on each card.  Did I mention that I love free money ;)

-   Alternatively, you can buy Amazon gift cards at cost if you use Amazon a lot for a return of 10% on each card.

Join Best Buy Rewards and get a $5 gift card for every $250 you spend at Best Buy (2% back). This purchase will qualify and get you $200 closer to your next rewards card!
