Nope.

Regular blu-rays will usually be sent in cardboard envelopes, or sometimes bubble mailers. Yona LE will probably be in the latter, and if it's like the one I got from them about a year ago will have corner damage from the process. I knew that going in though and mainly wanted it for just the inner slipcase and case+discs (since the regular edition doesn't have a slip) so wasn't too upset with the condition of the outer hard case.
Also they usually ship every item individually no matter how large the order, which given how they package is preferable. Very rarely they'll send multiple items in a box, and more often than that three or so loose in a big bubble envelope so they can make imprints on each other as heavy items get put on top during transit.
Bubble envelopes are the bane of my existence and I have far better luck with the cardboard envelopes. I know why businesses use bubble envelopes, but will never understand people who think that is good and safe packaging for discs like ebay sellers with rare Criterions or such sold at high prices and then toss it in a bubble envelope to ship.
The reasons to order from Rarewaves is something not found elsewhere or for lower prices if that's the case. If you care primarily about condition things arrive in then AL is greatly preferable.
I'm not in the UK so things travel further to me, so experiences could be better within the UK.
