FiveStar is also the shop I'm getting the best results with at the moment. I choose the 'no cases' option to avoid floaters.
But still the DVDs aren't in completely perfect condition. They play without any problems at all, but they're not... well, perfect. There's always some (usually very) minor scratches.
With DV-Depot everything was always 100% spotless. They shipped with cases, but they opened the cases and wrapped the discs in paper towels or, for a small extra charge, put them in cardboard sleeves.
In addition to those mentioned vendors, I find that Adult DVD Today package them very well. They put the discs in those little "folder-style" sleeves. Like the little paper ones, but the same as you'd find in carrying cases like this but instead of being bound into a pouch, they are individual double-sides "pages" with holepunches in them.
I ordered from Lasersedge using the "no box" option some months ago and when they arrived I found they just put the dvd between the cover art.
Everything was floating around with disc to disc contact. Fortunately they were not too badly scratched but greater care should have been taken to avoid any damage. Things may have changed since.
Not used Adult DVD Today for a while but when I did they were always put into paper dust covers and were very well protected.
scipio: I think I know those sleeves. Microsoft ships their MSDN subscription DVDs in very similar if not identical ones. They are nice. But MS also wraps them a few at a time in sealed clear plastic bags. That way the discs can't fall out of the sleeves. Do Adult DVD Today also package them in a way that they don't fall out.
charlie: Regretfully things haven't changed. Laser's are definitely out of the question unless they do change their packaging radically.
The way Adult DVD Today ships (recently at least, I can't remember a year ago) is that both the covers and the discs in their sleeves are shrinkwrapped together, so the discs/sleeves are nestled inside the folded covers, if you know what I mean. Also since the sleeves fit 2 discs, one on each side they're in there a little firmer then single-sided sleeves, so they can't easily move around.
I may have to try AdultDVDToday. That packaging sound almost ideal.
Their website is a bit of a showstopper for me though. It's nigh on unusable on Firefox and Konqueror. It most likely looks lovely in MS Explorer, but that's not an option as I don't have Windows at all.
Also checking out AdultDVDNow.
Funnily enough both ADtoday and ADnow seem to carry very few of the titles I've bought lately and am looking to buy in the future. But I guess I can just mail them and ask them to add any titles I'd like. That's never been a problem elsewhere.
