Just sold my 3 month old bicycle after posting an ad yesterday. I’m surprised at how quick OLX could get! I haven’t bought anything from there so I don’t know about that, but about selling, I repeat, its a good website. And as far as I’ve heard most of the users of OLX are people genuinely interested in buying and selling.
The website is quick, you can edit your ads after you’ve posted it too. Options to put up product’s photos are up as well. Not much time is taken for your ad to get published after you’ve submitted it.
