Mystery Shopping:
I've signed up for many of these but I live in Alaska and there are not many opportunities here! Additionally I suffer from Social Anxiety Disorder so ones that involve too much social interaction I can't do. Hopefully one day I can and 'Mystery Shopping' is helpful for me to force myself outside my comfort zone!

*More about Swagbucks:
Being a student, I do a lot of research so Swagbucks is just awesome because I make money doing my homework by using Swagbucks as my main search engine. With one research paper, I made enough points for a $5 Amazon gift card!
There are many ways to make Swagbucks: searching, NOSO, daily polls, downloading the toolbar, filling out trusted surveys, watching short videos, playing games, doing tasks, and even printing and using coupons. Every 450 points you can earn a $5 gift card, such as the Amazon gift card, or you can redeem points for other items. You can get bigger gift card amounts but the $5 is a better deal for the points!
You can easily get over 20 Swagbucks a day in about 10 minutes or less. (Which would equal more than enough for a $5 Amazon gift card)
Search - you can easily get 15+ Swagbucks per day
NOSO (you can skip all of the offers) — 2 Swagbucks
Take the Daily Poll — 1 Swagbuck
Login Via the Toolbar — 1 Swagbuck
Click on Trusted Surveys — 1 Swagbucks
Watch 10 videos on Swagbucks TV - 3 Swagbucks
Make Money on your Phone
I've recently discovered there are apps on your phone where you can earn points for prizes, such as gift cards. Additionally some survey sites also have apps to do surveys on the go.
