I have talked about Cashcrate before, but now there is another reason to give them a shot! For the month of April they are awarding the top 20 users with extra cash prizes (from $5 to $150).
The top users are the ones that earn the most with offers and daily surveys only. You can complete two surveys a day and you will get $0.80 each ($1.60 a day). There are tons of offers that. Remember that the best thing to do with the offers is to use an email address that is different than the one you use everyday. You will probably get a lot of junk mail sent to it!
