At the top of my Google homepage, there is a link for 'shopping'. I clicked it. I entered 2006 Artifacts auto Magglio. Nothing. same search with Dontrelle. Nothing. Same with Cabrera. Nothing. Lastly, same with Giles. Bam! A hit.
I clicked on the search result. It brought me to a Vendio site. I am not sure if it's called First Choice Collectibles or Sportscards Charleyyy. You can see the site here. A couple of clicks later, the Giles had been paid for with my PayPal account. $9 bucks. I was beginning to wonder if this card even existed. Since I have started to build this set, this is the first one I have ever seen.
My point is, there are more places to buy cards than ever before. Don't just use eBay, COMC, and Sportlots. Look around, you might find what you have been looking for. I did.
