"They were my same regular prices listed on my Web site"

Maybe they would have been if you had done the maths right.

"Did you ever stop to think that maybe some of those chips might have been bought long after the release?"

From your own email - "I think I still have them available" - didnt read to me as though youd got them more recently.

"Besides, the reason behind hoarding is to sit on the chips & then sell them at inflated prices"

I dont necessarily agree with this statement. Anyone could hoard chips just to prevent other dealers having them and subsequently drive people to their business. No inference of inflated prices.
