Multi-categorical These are the websites which fall into multiple categories as they offer many services.  The are my favorite way to make money online.  I use these the most personally as a way to consolidate the amount of money I make, I have found 3 sites that are reputable and have a good track record for payment.  I have found substantial proof of payment for all three of these.  They all have offers that you get paid to sign up for, the other factors vary by site.  These are what I recommend to people that ask me in person how I make the majority of my online income.  One quick piece of information, if you do the offers on the sites I would recommend setting up a privatephone voicemail system so that you will not get called at your house, and if you do the offers that require a credit card make sure to cancel as soon as possible so that you don't get charged the monthly fees.  These offers are completely voluntary and are not required to make money from these sites by any stretch of the imagination.  Hopefully you will enjoy them as much as I do.  These sites are my main source of revenue online.  They are easy ways to make money online if you have spare time.  They are well documented as paying out to users, I have not heard of many issues with these sites.

InboxDollars This website is one of my personal favorite for many things online, I do the $1 a day surveys, 100% free offers, and paid to read e-mails.  This site has a $30 cash out, and a $5 sign up bonus.  I've already recommended this site to my friends and family, it has become part of my daily routine, and as a result I get some extra more for energy drinks and ramen.  They average approximately $.04 per paid e-mail, I typically recieve 3-5 per day.  The surveys I suggest you take daily, you may not qualify every time but I've never gone a day without finding any surveys to qualify for.  The offers are fastest way to make money on this site.  If you plan to buy things online I suggest you do it via the cash shopping section to earn cash back for your purchases.

Treasure Troopers This site is similar to InboxDollars in many ways, it offers daily surveys, 100% free offers, trial offers, cash back on purchases, games, and it also has many mini-games on it.  I find this site to be the most fun as it has chances to win various pearls and coins which can then be traded in for real prizes such as $50 Visa Gift Cards along with offering the ability to get a check for the money you've earned.  When you hit $500 total earned you are invited into the "VIP Club" which allows you to make money even faster.  I highly recommend this site, I truly enjoy doing it and at the same time I am making money.  It is commonly referred to as "TT" on the web.  They have a good forum community and there are many people willing to give you advice and confirm the validity of this site and various offers within it.  If you do the free trial offers make sure to cancel in time unless you wish to continue the service.  This site has the most offers of the three, if you would like to put in extra effort for higher payouts, this is the site for you.

CashCrate This is a site that covers most of the same bases as the other two multi-categorical sites.  I'm signed up for all three of these sites personally.  The main thing that makes this site stand out between them is that it allows you to do 2 daily surveys per day, and as a result I make a little extra cash per day.  You get money for joining free sites, filling out surveys, completing offers, etc.  Well established with a good track record.
