Sorry........that was a bad post on my part. I don't know with any certainty that SB couldn't sell your shares for you. I recommend that anyone with an SB account simply call the brokerage and fact find. There's a logical answer. Sorry if I made you nervous.....apologies!
I called and talked to them at the Seattle office. She said "Price fluctuations" and Penny sub-penny. She also said they offer over 7000 stocks. Sounded like a commercial. No other problems...GLTA
