Just had major issues with getting a jersey from the States, have to say it's tough if you're not going in person and bringing stuff home.
My bro went to the Packers v Raiders game at Lambeau back in December and picked me up a Reebok Reggie White 92 throwback jersey. When he got back home (eastern US) he sent it on from his house, no problems delivered straight to me.
Unfortunately there was a problem with some of the numbers peeling off the shirt after a couple of days, so I sent it back to him and he sent it on to the Packers Pro Shop at Lambeau, who replaced it, threw in a Superbowl XXL t-shirt and a card apologising for the hassle, which was all a very nice touch that you'd only expect from an American retailer in fairness.
They then sent it straight to me, but unfortunately via UPS, who gave me a rather surprising phone call a week later looking for €43 excise on importing clothes from outside the EU!!
After a week of phone calls between the Pro Shop, my bro and UPS explaining that the shirt was a gift in the first place and had already been sent from America to Ireland and back, they eventually released the jersey, which I'm now very happy with, albeit 2 months after I originally expected to get it.
So unless you have an address to go thru in the States, I'd tread very carefully with using any of the online Pro Shops from here.
