CashCrate is an online system that allows you to cash in by completing free surveys and trial offers in your free time.  I started using them last year and can say this is definitely a great way to earn some extra cash.

I'd also like to dispell any rumors right now - Cashcrate is a legit company with upstanding business practices and timely payments.  They've never missed a payment since I've been with them and there has never been any sort of accounting or other issues.

A nice feature is the ability to filter by offers that are 100% free.  This means you won't have to worry about getting dinged with a recurring fee or being signed up for some extremely expensive "save the endangered poodle fart" organization.  Don't get me wrong, there are some non-free offers that look alright (and they pay extremely well), but having 100% free offers gives some people peace of mind who wouldn't be making money this way otherwise.

Oh yeah, and you can get a free dollar when you sign up so you can literally be making money online in no time at all.  It took me only a few minutes to sign up and start completing the simple little surveys.  Those surveys didn't pay much each, but it's something I can do while watching TV and you'd be surprised how quickly it adds up.

There is a second way to earn money with CashCrate and that is by referring friends, family members, and others to sign up using your referral link.  This idea appeals to me because the effort is only exerted once yet the rewards are received continually over time.  Even if you only refer a few friends, there's no reason not to.  The money can add up.

In conclusion, you won't get rich from getting paid to fill out surveys online, but it is a legitimate way to earn extra income.  If you're in a bind or need some spending money, this is a great option.  Another idea would be to do a little work (say $20 since that is their minimum payout) each month then just invest the money or save it for a rainy day.

Happy money making!
