Can we make a deal with you at a price around the market price on eBay?
If I decide to buy large quantities from you on a regular basis, I would like to discuss with you whether you could sell them to me at a price lower than the eBay market price.
Of course, I understand that we can't continue to do business with you unless there is a benefit to you too.
