I asked DH about this and of course, like a typical man, he couldn't have a simple answer. So, he wrote it down for me. He's been with Target for 21 years. LOL!!
Basically the debit card is treated as a check. You start out at a level 0. This means that you can write 1-3 checks/debit transactions per 30 day rolling period. The max amount is $100 per transaction and the monthly max is $250.
He wrote down all 4 levels. LOL!!
1- 3-7 checks/debit transactions $200 max transaction, $500 rolling 30 day max.
2- 7-10 checks/debits transactions, $350 max, $850 rolling max total
3-10-12 checks/debit transactions, $500 max, $1000 rolling max total
4- 12+ checks.debit transactions, $1000 max, $3000 rolling max total
To go up a level you must meet # of checks/debit transactions withing a rolling 30 day period. If one returned NSF fee in that 30 day rolling period, you go back one level.
I hope that makes sense...... LOL!!
