If you check on sites like slickdeals.net, you can often find listings for ebay deals on refurbished prebuilts like this HP. It's $319 with a 5600g, 12gb ram, 256gb ssd and 1tb hdd. Source: 6 months ago

You can absolutely find a better deal than that. That hardware is quite old for the price. I'd try looking at https://reddit.com/r/buildapcsales/ for the occasional prebuilt posted there, and sites like https://slickdeals.net/ have prebuilts posted as well. Source: 6 months ago

Note: If you want to pay more for better bass the Monolith 10" THX and 12" THX subs are on sale right now too-you can read the same audioholics review on both of those models. For home theatre bass matters the most, then a good center channel, then mains, then surrounds. A Speedwoofer 10S would blow you away compared to what you have and totally elevate your system immediately-the Monolith subs are more... Source: 7 months ago

I tried to post a deal on Kobra 2 Neo (what with the "singles day" 11/11 and Black Friday sales campaigns) to https://slickdeals.net/ , the deals site - only to see it deleted within a few minutes by a moderator. Source: 7 months ago

I honestly don't know if this is a bad-okay-good-great deal but I like slickdeals.net because you can read other people's comments on the particular deal and make your down decision. Not advocating, please do your own research. Source: 9 months ago

Right now I'm using services like Chatfuel.com and Adexpresso with FB ads, however, my conversions aren't great and I've gotten banned a handful of times. Twitter and Linkedin ads have also been hit and miss. I've also signed up for a couple of beta releases of ad networks on the blockchain (Primelabs, et al.). So on the waitlist for those.
