Postcard postage?

Question

How much does it cost to mail a postcard now? Can a few coupons be taped to the back?

Answer 1

I taped a business card  the back of a postcard and it made it to my dads neighbor OK.   So I guess you give it a try if you want.

Good luck!!!!

Answer 2

"Regular" sized postcards are 27 cents and large postcards are 42 cents in the USA.

Regular size = Maximum size: 6 inches long by 4-1/4 inches high.

Large size = More than: 6 inches long by 4-1/4 inches high

(copied and pasted directly from the US Post Office website - see below)

I would not tape anything to the postcard because all first class mail goes through a fairly high heating mechanism as part of the screening for illegal materials and tape on letters (to seal them up) often comes unglued (or so they told me at my local post office).
