I;'ve been up to 10,000 credits from Surveys
Down to about 5,000 now after gifting a few friends.
I do the 450 amo every day. If it asks geneder before age, dont bother.
If it asks age first, its going to put you into a movie survey
IF, you are 22yo, m/ f, that go to the movies more that 24 times a year
The daily surveys are great.
I'm usually between 24 and 31 yo .. once you finish one , clear the browser cache/ cookies/ history , go back and do it again
Keep in mind also the OFFERS.
GoDaddy - buy a domain name ($9) get 2500 credits.
Even if you wont use the domain name, thats a cheap $25 worth of credits.
Flowers? Do you need an excuse to buy flowers?
50 creds for every $5 spent. Two Birds, one stone.
