They are only interested in the money. What makes Heritage not ebay is that heritage sells everything like an auction house. Ebay is not an auction house.
Of course their is Ebay, where the seller pays all of the fees and increases the shipping cost. Since when is a stamp $1?
Ebay requires additional time sifting through junk, cleaned coins, or overpriced coins. Even with an advanced search. I prefer the quality of Heritage's offerings. Buddy, you can testify to the amount of cleaned junk all over ebay.
About 18 years ago, I was paying 10% as a buyer and thinking it was really high. I'm thinking most everything else has gone up much more over that amount of years.
