Lowe's advertises awnings, but they're more expensive than that. I see a listing for "144 inch wide x 120 inch projection x 10 inch height metal solid motorized retractable patio awning" for $426. (I tried switching stores from San Francisco, CA to Albuquerque, NM in case of location-sensitive pricing, but prices didn't change.) One meter is about 39 inches, so this appears to be a bit under double the area (including 50% more projection) for a bit over double the price. But the vast majority of their listings are much smaller without being cheaper. Even the cheaper one is one square meter for US$100.
