Well, I don't wanna be the bearer of bad news, but in all likelyhood, probably not. If the USPS system shows that the package was delivered, then they will go off of that information. Maybe the delivery person could remember if/where it got dropped off (if it was one box, a pink bubblewrapped package with Memebox should be hard to forget I would think) and that might shed some light on if it was misdelivered or stolen. If they can't remember, chances are, they'll just go off of what is in their system which will leave you right where you started. Is it possible for you to go into the local post office to talk to workers/delivery people directly? As for Memebox, their site specifically says under the Terms of Use, "We do not hold responsible for the delivery of merchandise once it has been delegated to a third party provider." which is their way of saying they wash their hands of stuff once it gets picked up by mail service. If you contact them they might give you points, but seeing as how many people on this part of MuT are having a problem with Memebox's CS and getting their points for missing/damaged stuff, it might be a long process. I'm sorry that you're having to deal with this problem and hopefully I'm utterly wrong and you get a replacement box or some good form of compensation for the trouble, or at the very least you find out what happened to the missing box.
