PBS money is used to pay for:

• Swap Fees. Swap Fees are 49 cents per requested shipment, unless you are an enrolled Standard Member with unlimited free requesting, or you have some Free Swaps (each Free Swap replaces a Swap Fee) in your account.
• Printable Postage, which allows you to mail your book from any drop box or from your residential mailbox (if your mail carrier collects packages). Printable Postage comes with Instant and Guaranteed Credits for accounts in good standing.  To apply the postage to your wrapper, just choose 'postage' when printing the address from the request. There is a postage printing fee assessed for printing postage, at the time you print the postage.
• Any Kiosk purchases, including PBS Market books and Book Credits.  To use PBS Money for a Kiosk purchase, just choose the "PBS Money" payment option at checkout. 

Please note: Purchasing PBS money does not purchase book credits automatically: to purchase book credits, choose the Book Credits item in the Kiosk.

Please note: Because the 50-cent Kiosk Transaction fee is "flat" ( = 50 cents no matter how small or large your purchase), it is wise to buy PBS Money in lump amounts ($5, $10, etc) to have Swap Fees and/or Printable Postage for several shipments before having to "reload" your Money account.  Purchasing "lump amounts" of PBS Money less often will minimize the number of Transaction Fees you will pay.
