This offer is for those with the Kindle Wi-Fi with Special Offers only. View the Special Offers on your Kindle (Menu, Special Offers) and you should see a new promotion (if you don't, turn on your wireless, click Menu, Sync & Check for New Items, then after the sync has completed, go to the Special Offers screen):

$10 for $30 of products in the Amazon Denim Shop (save up to $20)

Click on offer, then click on the link on the offer page sign up and get an email with the promotion code. Sign-up for this offer expires on May 12 (which is today).

You'll get an email (right away), with a promise to send you the promotional code within 7 business days. This is the same waiting period that was on the $1 MP3 album (check your emails if you didn't see this one come in; mine showed up late last night and I signed up for it on May 5. I'm now all set to get my album, but I'm holding off on entering the code until I'm ready to buy, as it will apply to the NEXT album purchased after entering the code, even if it was a $1.01 album (so you only save a penny).

In the meantime, you can check out the Get up to $30 of denim apparel sold by Amazon.com for $10 to get the full details on how the offer works. Note that you must put at least $10 of products into your cart (technically, you don't, but you will be charged $10 as a minimum, with this particular code). Once received, the code is good until June 12 (so, under a month, if it takes a week to get it, as the last one did). You also have to use the checkout procedure, so that you can add the promotional code (one-click orders don't allow promotional codes to be entered) and must have a Kindle Wi-Fi with Special Offers registered to your account when you place the order.

I poked around in the store a bit and although there are many of the >$150 jeans shown in the storefront, there were also a number of "regular" jeans in the $25 or so range.

Even if you don't qualify for this offer or just don't want to buy clothing thru the mail, be sure to check out the Win a $1000 Gift Card contest, for those in the US. Sign up for Amazon's emails and you are entered (cancel them after the end of the month, if you want).
