Customer request to purchase items before auction ended

I have received a message from an eBay customer asking if she can purchase multiple items that I have put up for auction at a fixed price before the auction has ended.

 

I received a message stating that she can't afford much and would appreciate the items at a certain price. Single mother on a disabiltiy pension.

 

Is this against eBay policy? I can't find anything on it anywhere.

 

I haven't sold much on eBay before and don't want to get a mark against my name because I didn't understand and feel sad for the lady and wanted to help her out. 

 

I also don't know if it is just a sob story to get stuff from people cheaper either. Oh the world we live in. 

 

Please help a new eBay seller out and point me in the right direction so I can assist the customer as best as I can within the eBay guidelines.
