It looks like NavyFed quietly got rid of their temporary "One Penalty Free Withdrawal" perk on their 18 month EasyStart Add-On CDs over the last few days. The rate's still the same (4.59/4.70) but the language about allowing one penalty-free early withdrawal from these CDs if opened during the promo period, has been removed and replaced with just the standard "Penalties may apply for early withdrawals from certificate accounts."
For those who opened one or more of these up during the "one penalty free withdrawal" promo period, you'll still be allowed one penalty-free withdrawal (partial or full) for each of these CDs you opened during that period. But any you open up now will no longer have that perk.
