How much does it cost to send fliers by mail?

Answer 1

That would be first class postage, 41 cents each, unless you are sending a large amount to specific zip codes, in which case you might be eligible for a bulk discount. Go to the post office website at http://www.usps.com and select the 'calculate postage' link - that should help. If not, you can call the post office and ask about bulk rates.
