MacMall.com is offering the Iogear 4-port USB 2.0 hub (high-speed, model GUH285) for FREE after a $7 mail-in rebate. The special is good until January 31st, 2009. They also have a few other items for free after rebate (three software packages and a power adapter for iPhone/iPod). You can find these by looking just below the product page at the section titled "Customers who viewed this also viewed".
If you are planning to buy more items, they also have a free after shipping promotion. Basically you have to buy $99 or more worth of eligible products and submit your UPS shipping fee for a mail-in rebate refund. This is good for shipping fees up to $40. See their website for all the details.
