Hello Howard Murphy,
that is indeed a good question. In my opinion, every merchandise has its buyer.
So to serve everybody, you need to have a variaty of items and prizes. From very low to expensive, why not. In that way, you can sell more than if you have just items with a lowest prize or items with the highest prize. Diversity of products will attract more buyers.
I hope my answer helped you a little.
Good Luck!
