Not sure what you are getting at, but the prices she gave me were after a good bit of negotiation. Sun Fun Kits price is $7500 - 125 = $7375.00 (I paid 7475 but sfk then credited me $100.00 today to price match the drop in price) no credit card fees or any thing, Luyuan was $7940.00 after she did some trick to lower the sales tax a bit, something about the shipment being under her shipping company's name.
option 1: sfk gave me a lower price plus I can call them on the phone and is a US company so if they screw me over I can file charge back, or take legal action and ship them back with in the usa if they arrive damaged.
option 2: Luyuan higher price, no phone, lets say the cells arrive damage, and then my credit card company tells me I have to ship them back to china? Seems to be an impossible task.
