ISO: Priority Mail Flat Rate Padded Envelopes

[surrealestate.livejournal.com]

I need some USPS Priority Mail flat rate padded envelopes. I recently discovered that, unlike the boxes and document envelopes, these are not available at local post offices. I have a pack of 15 on the way, but I'd like to be able to send a few things sooner than their estimated delivery date.

Do you already have a pack you can spare for a week or so? I can replace it as soon as the ones I ordered arrive. Thanks!
