How do I avoid wasting time when shopping locally?

For shopping around Sutherland Shire, start with what would make the trip easy. Specific local reference points from the existing Q&A include Gymea and Sylvania, Como and Oyster Bay, Engadine and Heathcote, and Cronulla Central Car Park. If you need something quickly, check parking, opening hours, stock, and whether you can do several errands in one stop. For a specific item, a specialist local shop can beat wandering through a big centre.
