The two boxes that I thought had cleared LAX customs last week were in fact sent back to Belgium and should be arriving back at Etre in the next couple days. That makes three boxes rejected by LAX in the last 4 months, with none accepted through LAX in that same time frame. JFK has been fine for me as well when boxes happened to get routed through there. One of the boxes sent back was marked in the USPS system as "Cannot be delivered as addressed" - I called in on that one and USPS has an open investigation, so I'm curious to hear what they come up with. The other box just silently got shipped back, hopefully there will be something on the box that tells Etre what happened.
I'd be really curious to see if anyone has any tangible advice or ways of alleviating the problem. I realize that buying beer online and having it shipped here is in a legal gray area at best (probably not even that, but let's be optimistic), but I've never had issues like this in the past. If it's something where a fee could be paid or using a different carrier would bypass the issue (eg, if USPS is the issue rather than customs), I'd probably be willing to pay a little extra to guarantee delivery and avoid the hassle of having to ship boxes twice.
