I ordered the Kaizen rashguards too. Great deal, couldn't pass it up. The standard $10 (+5 per additional item) shipping also takes about a month or slightly over for me, so I don't expect to see the rashies till mid April.
I've never used the FedEx shipping method yet, but I've had bad experiences with private couriers in the past. If it was just an additional 15 bucks to the shipping cost, I would use FedEx all the time, but they end up collecting anywhere from $30-50 in customs brokerage fees when it gets to my house. Almost as much as I paid for the actual items.
