I don't believe you have the correct pricing for usertesting.com.
I wish it was as little as $5... maybe if you have a $20,000 contract with them... I believe its $30 per test for 15 tests. After your 15 tests, you have to pay an additional $5k licensing fee + $30 per test. The more you order at once probably will lower that cost per test, but it will cost you.
