I work with a lot of GPT and paid survey sites. Cash Crate is my absolute favorite, though.

Cash Crate's site is super easy to navigate, they pay via check and do not charge a fee for the service, they have a ton of offers to choose from, they offer 2 daily surveys that each pay 80 cents, and they pay you super fast!

The best part about Cash Crate is that unlike many other sites, it isn't tricky to get your offers and surveys to clear. I never have to worry about deleting my cookies with Cash Crate.

There are 2 things that you definitely have to do with Cash Crate to earn the most possible: 1) be sure to go back and click the submit button from the offers' list on Cash Crate's site after you've completed an offer or you won't get credit (tip: Cash Crate won't let you submit unless you have at least looked at the offer, so sometimes it's a good idea to just go down the list and click submit on all of the offers just in case you forgot to submit one that you did), 2) be sure to check your email because some of the offers require that you verify your email address before the offer clears.

Cash Crate is super easy and pays fast. Even if you aren't looking to spend a ton of time doing GPT and survey sites and you sign up for only one site, be sure to make it Cash Crate.
