We send out checks on the 11th of every month, but only after your month-end balance reaches at least $50 USD. If my account balance is $40 at the end of January, I won't be paid on February 11th. If I earn $20 more in February I will be paid on March 11th for $60. Then if I earn $200 more in March I will be paid $200 on April 11th.
Make sense?
