I doubt you're going to get them for $350... I contacted the seller out of curiosity for his location. This is the message he sent me back
DC/MD/VA area. About 15 miles away from DC downtown. If you have friends here they may do a cash and carry deal. Otherwise just stop by my place and get it. I list this in bimmerfest dot com asking for $480. I consider any reasonable offer and may end this auction any time soon if someone makes a deal with me from that site. Where are you located by the way?

You might be able to haggle him down to $400.... but with shipping, you're looking at $500+ (Unless you're in the DC Area).
