In any case, I've found that their silver age backissue
list is nowhere near as complete as it used to be.
The last couple of orders I have done, I found that they
were out of stock of half the isssues I wanted,
and so I placed my orders with Lone Star comics
instead, and I think I will now continue to do so.

The only time I will order from Mile High now is if they happen
to have an issue, I can't find elsewhere, but that still
happens often enough to use them semi-regularly.
