I've bought my first electric guitar (an Ibanez Gio) for quite a cheap price in a Facebook buy and sell group. All you have to do to join such groups is type your country on the search bar and add "buy and sell" or "for sale" and click on groups. You then will have to join one and check out the items for sale. Take note that most of the items in those groups are used, so if you want to make sure of the quality, always ask the owner and inspect the photos first. I myself am happy with my electric guitar, I think it's alright for the price. The only downside for me is that some strings go out of tune very easy when I bend the strings a lot during certain songs.
