Cost to mail a single chip in a size 000 bubble envelope is $2.32. $0.98 if you go to Queenie the Clerk at Victory Center Station on Lankershim Blvd. in North Hollywood. And $1.19 if you find the Relief Clerk at Sun Valley, CA, on a Saturday. USPS seems to charge whatever it pleases.

Don't try just sticking two 49¢ Forever stamps onto the envelope and tossing it into a mailbox. That won't work, ever.
