The following phrase:
“An electronic check (E-check) is our most popular method of account funding. If it is your first deposit, you can get up to $500 in real-time funding. Two weeks after your first check clears, you can receive up to $1000 in real-time funding, providing you have not had any returned deposits. Withdrawals will not be made available for 14 days after bank account information has been initially provided or changed. Real-time funding is limited to a maximum total amount of $500 or $1000 per member at any time. Please contact us if you have any questions regarding E-check deposits, real-time funding or withdrawals.”
To be clear this is not a bonus. It is saying how fast they will credit funds to you.
If it is the first time you are funding lets say you deposit $1,000
They will credit to you $500 immediately and then in about 5 days when the check clears the other $500 will be credited.
After that lets say you put in 2k - they will immediately credit to you $1000 and then deposit the remaining 1k after the the check clears.
Its not a bonus of additional funds its real time funding of your deposit on the check before it clears up to a certain amount.
