I use the Priority Flat Rate Mailer which is $4.75 (if shipping label is printed on USPS.com website) & if using the website, you get "free" Delivery confirmation. I can get a couple soft cover books in the Flat Rate Mailer & the mailer is free. There is now a "legal" size Flat Rate Mailer that goes for $4.95 & a Flat Rate bubble envelope for $4.95.
