For the same reason Mercedes dealers don't sell Kias. Would you want to explain to every customer why each panel, rated similarly and looking much alike, is superior to the other one you carry?
When your making 10% on each panel, the advances cause you to be careful in how many panels you stock, frankly on EBay he could have said he has 1000 of them. Makes you look like a big player, which he may be.
Do the math, to sell a panel with free shipping at $100, it works out like this:
Cost of shipment to customer: $6
Cost of shipment from China per panel: $10 (minimum)
eBay seller fee; $5
That leaves $79
If he makes $10, then the panel has to cost him $69. That's if you ship in volume, too much and your shipping tanks your margin. He's tweeking his pricing based on demand and shipping costs.
