How does walmart ship it's blu-rays

[leest3]

Hi All,

I am just wondering if anybody knows how Walmart ships its blu rays.
Do they ship it in a bubble pack, a cardboard box, or a cardboard envelope mailer (like target does)?
I've basically given up on Amazon to deliver a blu ray without damage to the slip cover. Target ships it in the cardboard mailer and they've come flawless.

Any feedback would be greatly appreciated.
