I bought 540 for my build. I got them directly from Loraine. Everything totally above board. I had them sent directly to my house by air. The cost (including shipping, taxes and brokerage which Loraine took care of) was less than anything I have seen for sale domestically. I could have saved $2 per cell if I wanted to wait a few months if I had them sent by boat. You can always email her and ask. She usually answers quickly.
