Here are some great tips that you can follow to actually get your free stuff from sites. These techniques will help you stay organized and informed.
Do some research about the different networks
Search google for different networks (i.e. Nuitech, RewardsGateway)
Don't assume just because some people say they had bad experiences that the network is necessarily bad.
Make sure you check the entire site before you complete any offers to make sure you will be able to actually complete the site.
Check how many offers will be needing to be done
Make sure you document each offer you complete
Print screens can come in handy
Save ALL confirmation emails
Document the date completed, date needed to cancel if you decide to not continue on with the offer company. I recommend creating a spreadsheet. (or download this template)
DON'T cancel offers immediatly. At least try out the services or products. If you cancel too quickly they will catch you and you will probably get disqualified and you will get nothing.
Don't expect to get something for absolutly nothing
You generally must purchase something. It can be done to receive products for absolutly nothing but it is much more difficult. But great prizes can be gotten extremely cheap.
Don't expect to get something too quickly.
Expect a wait depending on the network from anywhere from a month to receive your prize to many many months. However, its important to keep in mind that you WILL get your prize eventually.
Research, research research!!!
You will never learn if you don't read about different networks, offers, ect...
