The Bottom Line I would recommend this site, they have been good to me. They have a few nice prizes that you shouldn't have trouble getting enough coins to win.
Qool is a good site for getting phone cards.. I've gotten about 30 of them so far in about a year..
You earn qool coins and use those coins to bid for items they have up for auction.. There is a wide variety of items but many of the expensive items will cost more coins than I will ever earn.
The program in the past had many opportunities to earn coins but most of those have dried up. No more banners to click on, you could get 100 coins for logging in (NOW it is 50.)
You can get 100 coins per day for 10 bids. They do send emails now with links to get more coins. Some for just clicking a link but most are for signing up for things, which I don't do.. I feel there is not enough reward given to make this worth the effort, plus many of them want credit card information which I won't give. You can also shop through them for qool coins. You can send referral emails to people and earn 50 coins even if they don't sign up.
I have won and received watches and many phone cards. I have seen where some people have never received their prizes but I have had no trouble with this so far.
Their customer service has been very good to me. I had bid on some items that I felt were not described properly. I did not received what I had assumed I should have and emailed Qool about this and they gave me double coins back, so I am pleased with their customer service.
Their site is very easy to use and navigate.
