Integra Car Cover Help

Please help me!!!!!

I'm getting sick of washing my car (97 Adriatic Blue Integra) like every week so I was wondering if any of you out there use car covers? If so which ones and what price? I called Acura and they said they'd sell me one for 160 bucks. Maybe I can find something that works as well but is cheaper? I park outside two weeks of every month so i need something that will keep my car from geting wet or dirty. Thanks in advance for the help.
