There is no substitute for snagging or cast netting your own. Be sure to buy enough. I will rarely leave the dock with less than 20 pogies. Cut your bait into thirds or quarters and hook the chunk through the meaty portion. You're now ready for action.
Technique can be important here.
If the current is not pulling your bait away from the boat and into the reef, you are probably fishing the wrong tide. Don't leave yet. You may produce fish even if the tide isn't quite right. Don't allow your bait to sit on the bottom. A light thumbing of the spool can be used to allow the bait to tumble in the current and appear more natural.
