I thought that they ship with no signature required. Did you order the Fedex option for the shipping? You would probably have to sign for it. I believe they offer two forms of shipping, regular airmail and fedex (which is considerably more expensive, I think $40!). Maybe you accidentally selected the fedex option or they shipped it that way in error?

Either that or they started shipping registered due to seizures. There are many posts on the boards from the past regarding an extremely high rate of seizures from this company.

In any event, I wouldn't be that concerned. If they wanted to seize the meds, they would have reshipped you empty boxes, as many other members have experienced with their orders. Most likely, they either didn't realize that they were Nurofen +. Nurofen makes a pain reliever with no codeine added as well, so they may have mistaken it for that. Or you may have gotten a nicer customs agent that figured that such a low dose medicine wasn't a big deal.

Did you order a large amount? Maybe they sent it registered because they didn't want to get burned by a big order if you claimed you didn't receive it and did a chargeback?

Don't worry so much! You are going to be fine!
