Via NihmRodd of FW. I haven’t used my account in years, but this worked on my account even with a zero balance. Not a bad idea to spur on some activity, and $50 return on $400 within 3 months is a really good return on investment, better than any savings account. Note that if you make any withdrawal from your account during the promotion timeframe (September – December), you won’t be eligible to receive the bonus.

Don’t have an account yet? Check out this $50 bonus when you open an new Sharebuilder account and deposit $50 before 12/31/11. After you open the account, try and apply the promo code above to get both bonuses.

You can grab an easy 150 Delta Airlines Skymiles by visiting this website and watching a quick video about $300 Bose QuietComfort 15 noise-canceling headphones. Earn another 350 miles if you stop by a Bose store and do a live demo. Delta miles no longer expire, but hey it’s free. “Offers valid August 29, 2011, through September 12, 2011, while miles supplies last.”

Discount stock broker TradeKing.com will be offering their customers free trades for all of Friday, 8/12/11:

In appreciation of your business, this Friday we’ll be offering a special free trade day for all clients. Any trades placed throughout the day on August 12 will be absolutely free of commissions. How it works is simple. If you trade on Friday 8/12, you’ll see the commission charged as usual. As of Saturday, 8/13, you’ll still see the trade in your Account Activity page with all commissions waived.

Trades are regularly priced at $4.95, so it’s mainly just a nice gesture. New clients should grab the $100 bonus they have for August 2011 and also the transfer fee rebate if moving money from another broker.

Sprint has some sort of group-buying promotion called Sprint Ticket Takedown (expired) where the more people register their e-mail and cell number, the lower the price of a movie ticket you can get from either Fandango or MovieTickets.com. You can register any time before 8/14, but you must come back on 8/15 to buy the tickets. One day only.

According to the fine print, only 100,000 tickets will be available, and each registrant can buy two. As of 8/9, there are already over 87,000 registrants. If that number reaches 95,001 then the ticket price will reach the lowest possible $4. I think that’s a pretty safe bet, so you’ll probably want to come back pretty early on 8/15 (opens 12:01am Eastern, so even late Sunday night for some). (Update: It worked, I got two tickets for $4 each at Fandango.com. Sweet!)

This is the story of how I ended up buying an Amazon Kindle with Special Offers (WiFi) today for $114. I am one of those guys that loves the feel of traditional books and really didn’t know much about eReaders. I figured the Kindle with Special Offers basically meant it came with ads. How annoying! But it turns out the ads never show up when you’re actually reading an book, and the “Special Offers” include some pretty good deals (mostly coupons good at Amazon). Past offers include a $20 Amazon gift certificate for $10, or any mp3 album for $1.

Right now, if you have a Kindle with Special Offers and “claim” it by 11:59pm Pacific August 8th, you can get 20% off select laptops at Amazon. The list actually includes laptops from Apple, Dell, and HP. Thus, if you were going to buy any laptop $570 or higher, this Kindle would essentially be free (plus more deals in the future). Apple laptops rarely go on sale, and you could be getting a $1000 Macbook Air for $800. The highly-motivated could probably buy/resell a higher-end Apple laptop on eBay and make some decent profit. (This is how I paid down a lot of student loan debt during the dot-com boom.) Some folks have been buying just the unique coupon code itself from owners for up to $50.

Of course, today is already August 8th, so to participate you’d have to buy a Kindle today from a retail outlet like Best Buy or Target. Some Apple laptops on Amazon have been going in and out of stock, but you have until September 8th to redeem your coupon.

(Update 8/9: The 20% off laptops is now over. The current offer I see is $15 of $30 in School Supplies at Amazon and $5 off Kindle lights.)

In any case, with some discipline hopefully this Kindle thing will continue pay for itself and my travel bag will be lighter. eBooks are only slightly cheaper than paper ones, especially if you consider resale value, but I do buy around a book a month. I’ve also thought about writing some cheap 99 cent eBooks for the Kindle bookstore. I haven’t even started reading about ways to hack this thing…

Here’s a question I couldn’t get a clear answer to… If you have a US Kindle with 3G, can you use their included web browser internationally? It seems to promise that you can buy and download eBooks over 3G abroad in 100 countries, but I’ve read conflicting reports about web browsing. If I can, I would be very tempted to upgrade to the WiFi+3G version with Special Offers. I know that with 3G coverage across the US you can do simple tasks like check your email on the road, which can be useful for the non-smartphone-with-data-plan crowd.

If you’re flying on Delta airlines in August over land, use the promo code DIETCOKEGOGO up checkout to get free WiFi inflight internet. Valid for Gogo Inflight plan of $12.95 or less (24 hour pass).
