Went into Morrisons and they give you wonderful large almost clear bags at the check out. They will be just the ticket to keep a few early courgettes happy. Tesco and Sainsburys ones are useless. Not only that they are strong enough to reuse. Tesco ones are hardly strong enough to get between the cash desk and the trolley.
Though I will use a plastic bottle cloches and fleece as well if necessary. I have also been known to dash out late a night with plastic milk bottles of warm water as well.
