Another site worth checking out is BookScouter, which will check the selling price on 55 different vendors. The list will include the offer price, how they pay (Paypal, check, etc.) as well as whether they pay for shipping and under what terms. If you have a lot of books to sell, they can search up to 3000 ISBNs in a single request if you upgrade to BookScouter Pro. There is also historical prices too in case you want to review trends.
First off, I’m a blogger so it seems wrong not to mention it, but more importantly, it’s a legitimate way to make money. It’s quite possibly the least straight-forward way on this list, but it’s very doable and it’s also quite possibly the funnest way on this list. I love blogging and I know hundreds of bloggers who feel the same. So let’s talk about making money blogging and what it really means.
Number one on the list is also the easiest survey site to sign up for. Once you're in you can take surveys and get paid at Survey Junkie. It's possible to make $100-300/week completing surveys on Survey Junkie! All you need to do is instantly qualify, then view exclusive offers in exchange for your opinions and get access to paid surveys, clinical trial opportunities, and other work offers. Survey Junkie’s interface is super smooth and intuitive (unlike the majority of survey company websites that look like they were built in 1997), and members are paid in cash via Paypal. Oh, and Survey Junkie also has an 8.9/10 rating on TrustPilot — the highest of any online survey company. This is one is the more reputable survey companies out there and I use it often.
