I'm new to this forum, and very excited to participate in discussions here
I have a great tool to tip you all about, a new website called Statricks that I've just signed up to be a beta user for. This site is fantastic if you (like me) use online marketplaces to sell stuff you don’t use (or your children have outgrown) or browse for good deals.
They provide you with price trends and fair market values for almost all used goods so you'll know what the going price is for an item. I find this very useful and reassuring, as I'll know I'm not overpaying or underselling my stuff.
You should check it out, and I highly recommend this site for bargain hunters
Happy money saving everybody!
