As a lefty, I've learned that if you want a guitar, you'll get it online and you'll like it. I've ordered from Guitar Center and from Sweetwater and I'm happy with what I got, although I'll be the first to admit that as a newbie, I could have purchased a total dog and not been smart enough to tell the difference.
I've only been playing for two years, and I started at a relatively advanced age for doing so (48). I highly recommend justinguitar.com for starters. I also play a lot of Rocksmith 2014 which is a lot of fun and quite useful but I wouldn't rely on it alone, as it is pretty weak at theory and teaching rhythm.
