I do the surveys (all of them) every day.
Sometimes you get lucky with the 450 Ampario.
Currently as of this date the DAILY SURVEYS are paying out multiple times a day. (75cr)
I clear my browser cookies/ cache/ history etc and reload the browser (or use a different one , or do all the above multiple times with three different browsers and earn creds from DAILY SURVEYS multiple times.
I also use the Florists offer. Keeps the GF happy and I get value with credits earned.
I have bought a domain name $10 for 1750 credits - BARGAIN
lol, even if you dont want a domain name thats $17 worth of creds for $10
Quickflix, never paid for me - even after multiple emails and screen shots sent to Trial Pay - no payout, so cancelled my account with Quick Flix and told them why.
Sampilicious surveys also ripped me off once and after multiple emails with Trial Pay I was awarded the credits.
Take screen shots. Be persistent when you contact SUPPORT.
and do the Surveys DAILY.
I am the same as others here , probably spent more than 10,000 in creds (gifting to RL friends etc) since I joined in Dec 2010
I have all i need right now as far as equipment, I am kept well in Callaways (10 in reserve) and I have 2200 surplus credits. I STILL do the surveys daily and/ or the offers regularly)
