Richmond Postal Credit Union is listing some competitive certificate rates. The highest rate is 4.20% APY for a 12-month Century certificate with a $100K minimum and a 60-month share certificate with a $500 minimum. For the 12-month certificate, a yield of 4.10% APY is available for a $50K minimum and 3.90% APY for a $500 minimum. Other competitive CD yeilds for a $500 minimum include 4.00% APY for 24 and 30 months, 4.10% APY for 36 and 42 months, and 4.15% APY for 48 and 54 months.
These share certificates also have a nice penalty-free withdrawal and additional deposit feature:
For Share Certificates only, a one time per year withdrawal of $500 or more is allowed, and a one time per year addition of $500 or more is allowed without penalty if the minimum deposit requirement is maintained.
So it appears this feature may not apply to the IRA certificates.
In addition to certain Virginia Post Office employees and retirees, membership also appears open to "persons who live, work, worship, volunteer, or attend school in, businesses and other legal entities located in the City of Richmond, Virginia." This is mentioned in the last part of the long field-of-membership paragraph. Please refer to their About Us Page for more membership details.
The credit union is federally insured by the NCUA (Charter # 66929). It has $79.5 million in assets and 10,118 members.
