Cheapest Photo/Document Mailers?

[HausofAriella]

I've been looking for cheap (but decent quality) photo mailers for my 8x10 prints. Right now I'm buying them one at a time from Walmart, but that really adds up. I've been looking around online, but once you factor in shipping nothing seems that much cheaper. Where do you buy your photo mailers from?

Does anyone have any suggestions?

I am a long-time loyal fan of http://www.papermart.com :)
They have a few different sizes of the stayflat envelopes and you get a price break for $200+

ULINE is probably also a good place to check out,

I found some U-line mailers here on Etsy - someone was selling their extras - might be worth a search. For anything larger then 8x10 I use round tubes - as they don't bend in the mail. Those I bought on Amazon.com

Thank you! I just checked out both and U-line looks like it's definitely the cheapest option for the size I need.
