It’s BACK!!!! I got it last time, and was able to get it again!
Go to the FREE $5 Amazon Instant Video Credit page and connnect your account to twitter, send a quick tweet and you’ll get the credit added to your account automatically! You can only do this between today and September 2, 2011, at 11:59 PM PST.
Once you get your credit, go to Amazon Instant Video Page and select a title, although the price on the “Buy” instantly button will not change, your credit will automatically be applied to your purchase. After your purchase, you can confirm credit was applied by checking your order confirmation, which will be sent to you by email.
I personally just did this and rented Rio for my kids, and got the order confirmation that they used $3.99 of my credit and so it was free!
The credit expires on October 31, 2011, at 11:59 p.m. PST. The credit will be automatically applied to your future eligible rentals until the credit is used or until it expires (whichever comes first).
