Does Walmart sell forever postage stamps?

Can you use stamps to send a package?

• I usually just use the flat-rate USPS boxes to send things that I sell on ebay,and print off the postage right on ebay,slap it on the flat rate box,and off it goes. HOWEVER,I have about $20 worth of .33 cent stamps,and nothing to do with them. So can I (for instance),take a medium flat rate box (the shipping for a medium flat rate box is $10.50),and just put $10.50 worth of stamps on the box and ship it? I'd have to put more postage stamps than what the cost of shipping the package actually is,so it would be the $10.50 PLUS,probably like an extra .50 cents or so. So,I just want to use up these old stamps,and save a few bucks,instead of paying for postage online or at the post office. I have no use for them,so I'd like to just use them up,and I have a package I have to send anyway...so is that an option? Will it still be sent priority,just like they always are on the priority flat rate boxes I'm using? Thanks!

• Answer:

  ALL stamps are still worth the face value. You can put $5 worth on a $10 package, and pay the balance at the Postal window. So, no need to put extra on. The PO does not care how you pay for the postage, via Paypal, stamps or cash for a meter-strip. Rich
