Don't cut lettuce with a knife; tear it instead. Before you refrigerate it, put it into a plastic bag and twist to seal. It will stay crisp for quite a while. The same technique works for celery and other vegetables. There are special lettuce containers available but they're a waste of money; a simple plastic bag does the job just fine.
Submerging lettuce in ice cold water will help crisp it up and make it crunchy. The cold temperature will help to revive wilted leaves and make the lettuce more refreshing to eat. It's a common technique used to freshen up lettuce before using it in salads.

No, lettuce is not cut when it flowers.Specifically, the lettuce needs to be cut before it flowers unless you want it to taste bitter and unless you do not want the seeds. A lettuce that flowers should be allowed to seed. A lettuce that is cut before flowering may regenerate seconds if it is a particular variety, such as butterhead and looseleaf.
Lettuce can withstand temperatures as low as 32F (0C) before it is damaged or affected.

The supermarket would probably close until they have enough stock to sell for a long time.
You will have to find a kiosk or till that is still operating and pay there instead. If you are unsure, you should find a member of staff to assist you.
