Cheapest way to buy stamps

[Benjamin Cowles]

probably a silly question but I haven't really shopped for them. I'm assuming the post office but I know the private post offices and grocery stores sell them too. I guess I'm wondering if they'll tack on extra charges, if they can, to them. Also it'd be good to know if any ways to get discounts on them if at all available. Any tricks, tips? Or do you just go grab a "book o' stamps" wherever they're sold? 

Also while I'm on the subject, I've learned that post card postage is cheaper. So... do you buy a different stamp for that? Again, and I hope you can't see me blushing, but I don't wanna fall prey to some street corner stamp peddler lol. I typically fall for con artist's tricks.

Hi @Benjamin Cowles,

If you are willing to do some searching, I bought ALL my stamps off of Craigslist. The forever first class stamp is regular $.49 but I purchased them from Craigslist anywhere between $.30 to $.40. I found a site that searches all Craigslist listings in all states and ask the people to ship them (if they are willing and don't think I'm a scam) and I offer to pay via PayPal or COD. Even paying for shipping comes out cheaper. Think about it, I'm buying 3k stamps for even $.40 and I'm still saving. 

If you don't feel like searching, you can still get a 10-20 percent discount on eBay. Good luck!
