Coppermark Bank is no longer doing business under that name because it has been merged or acquired. See the successor institution Prosperity Bank (TX).
I am glad I called to get more details on this account. The account exec told me 2 things that I wanted to pass on to others considering this account. First, is they can change their rates whenever they wish and don't have to forewarn you like on the previous statement. Second, the bank monitors these accounts to make sure you are using them as a true primary checking account. The rules are not written but if you plan to keep your balance near the upper limit, make just your required debit card purchases and direct deposit/bill pay, then they will say you are using it more like a savings account then your primary checking account and will switch it to one of their non-high interest accounts.
in response to txtooker's comments about hidden "primary account" requirements-- so far I have had my account two months, keep it topped up to $25,000 make nothing but 16 $1 purchases and required direct deposits, and have received my interest as advertised. I even transfer the interest to another account to avoid getting over the $25K limit.
There's really no risk here, except the risk of receiving the interest for a few months then having to move your money somewhere else. But that could happen anyway as interest rates rise and fall (mostly fall)
Everybody I have referred including my parents loves this account. It is the best deal going. Over a year now with no changes. Superior customer service When I go in I am called by my name.
Joined in late October 2011 and we've had no trouble with this bank since joining. Our interest payments are deposited each month and the staff has always been very friendly and helpful.
The staff even encouraged us to open a second joint account once we reached the $25,000 cap to get the most interest possible. (They allow up to 2 accounts per household)
Their locations can be limited/inconvenient, and their online services are somewhat lacking (lackluster website and generic iPhone app that isn't worth downloading), but I would still rate this bank at 5 stars due to the high interest rate and great service.
Also, just an FYI, some other reviewers have complained about transactions needing to clear by the 29th. As of April 2012, they have changed that restriction to be the last calendar day of the month, or the previous business day before the last calendar day.
We do not have health information for Coppermark Bank, because it is no longer an operational bank.
