I've got:
Like A Virgin
True Blue
The Immaculate Collection
so far; I saw a ton of 80sdonna singles at a small used bookstore about a month ago, but I don't really "do" 45s so I passed them all up.
It's going to be a slow process for me. I'm so tight with money and Amazon asking $50+ for some of her more recent vinyls.

No ma'am, not before a few drinks at least.
