...Going on a trip to Paris and wanted to know on what days shops and stores typically close. Particularly on the Champs-Elysées.

"Typically stores are closed Sunday and Monday especially if they are open on a Saturday. Tourist shops will be open 7/7 but the "general rule" is as above. also, stores open later here. Retail stores open at 9:30 or 10am."
