We talked on the phone !!!

Lindsay	Did you receive any feedback from Kate about pricing and samples we sent last week ?
Michelle	Yes, we just talked on the phone. She has received our samples and she thinks they look good. But ...
Lindsay	But what ? What's her concern ?
Michelle	She thinks both our pricing and minimum order quantity are too high. She needs to know if we can requote the price.
Lindsay	If we could requote the price, could she accept the current MOQ ?  [MOQ] = minimum order quantity
Michelle	She didn't confirm, but she said she would try her best to convince her boss.
Lindsay	OK, fair enough. Tell her we'll send out the revised pricing by today.
