Awesome buy.
That happened to me before as a seller, I switched from fixed auction price to an actual auction and forgot to change it, so I listed my Cal Ripken Jr. SGC 84 Topps RC for $.01 BIN lol someone took it within like 5 seconds. Luckily I told them it was a mistake and they didnt hold it against me and I re-listed.
I hope if the guy has a story like mine that you dont force him to sell, I doubt you would though.
If not.....GREAT STEAL!!!!!
