This is somewhat still on the topics here at Deposit Accounts. Many of us do buy BROKER CDs and Treasuries.
I traditionally use Fidelity, Schwab, TDAmeritrade, but have also used Merrill Edge, Van Guard, Ally Invest, and Interactive Brokers, but have discovered major problems with customer service (these last four) and looking for another source that has both CDs, Treasuries, and actually have someone you can reach on the phone.
? Should I try MORGAN? Are there others you use where you like offerings and the customer service??
-thanks
