All year long, we've challenged you to save more, cut impulsive spending, and even earn some extra cash by cleaning out your closets. For this year's final Ultimate Money Challenge, we want you to gift yourself - with savings. In other words, save a portion of your holiday spending.

It's November, which means it's time for another brand spanking new money challenge. This month, we want you to reward yourself - with savings, of course.

The end of the year is approaching quickly, and as we get closer to December, we want to focus on saving for the holidays. So this month, our challenge is simple: Clean out your closets and make some extra cash while you're at it.

Last month, we challenged you to save money on your mobile phone bill by switching to a cheaper plan. This doesn't necessarily mean you have to switch carriers, though. You might be able to negotiate a better price with your current one.

Readers, this month we've challenged you to save your spare change, and believe it or not, we're almost halfway through July. We've rounded up some creative ideas to help you stay motivated during the second half.

Happy May, money nerds -- it's time for our next challenge. This month, we're bringing back a classic. We want you to flex your negotiation muscle and start haggling.

We have just two months to go in our Ultimate Money Challenge. As we near the year's end, we're focused on holiday spending. This month, we challenge you to clean out your closets, get rid of some junk and make some cash in the process.

This year, most of our money challenges have focused on saving, from your mobile phone bill to your restaurant spending to your debt interest. This month, we're throwing out a different challenge: Come up with a holiday spending plan.

We've been throwing out a new challenge every month since January as part of our year-long Lifehacker Ultimate Money Challenge. This month, we're taking on a specific expense that's easy to cut: Your mobile phone bill. We challenge you to find a cheaper plan that offers the same level of service.

This year, we've challenged you to haggle your bills, tame impulsive spending and even save for retirement. Many of you have saved hundreds, and some of you have saved thousands. This month, we're taking it back to the basics with an old school challenge that everyone can easily join: Keep the change.

Last month we challenged you to haggle everything, and some of you saved hundreds. We're impressed. This month, we have a guest. Jim Wang of Wallet Hacks joins us, and we challenge you to use his "Upgrade and Save" strategy.

So far this year, we've challenged you to cut your bills, curb impulsive spending and even save for retirement. This month, it's time to hone your haggling skills.

With our year long Ultimate Money Challenge, we're challenging readers to a different personal finance challenge every month. This month, we're taking on debt. Let's cut your debt interest rate.

So far, all of this year's money challenges have been about saving money. Saving money is great, but personal finance has to do with so much more, and one of the biggest areas people neglect is their retirement. This month, we're challenging you to finally start saving for it.

February's challenge wasn't an easy one, but if you joined you may have saved hundreds, or even saved thousands! That's why we started this in the first place: to take action and actually save (and earn) some cash. We've shared a lot of advice on how to curb impulse spending. Now let's take some action.
