Not sure if anyone else with BofA uses this feature. Whatever dollar amount you spend the bank will round up to the next dollar and put the difference from what you spent to the next dollar into savings. If I used my debit card and spent $4.22 BofA will round up to $5 and put the remaining $.78 into savings. I just looked up my account and it says since enrolling in the program I've saved $1300! Not bad!
