I recently snagged a rare Zack Wheat oddball already in a PSA holder off of eBay. I've been lucky to land some cool and rare oddballs of numerous PC guys in the last couple of months and I can see myself trending in that direction over the last year or so when it comes to buying vintage. The price was most definitely right on this one and I'm beyond happy with my latest pickup.
The seller had the card up for quite some time. He eventually dropped the price by a fairly significant amount but I decided to wait until I had some extra funds.
