Not very often.
At least, not for me.
That wasn't the case for a blaster I bought on Friday. I saw the freshly stocked card aisle at Walmart and it had plenty of 2013 Topps Update blasters so I bought one.
I got two cards of note.
The 6th pack had this Yasiel Puig Walmart blue parallel. Not too shabby I suppose.
The bonus pack had this Cal Ripken Jr. Rookie Card reprint manu-patch thingamajig.
I looked both cards up on Ebay and decided to list them in a one day auction.
The Yasiel Puig sold for $10.50.
The Ripken, which I started with a price of .99 cents and a buy it now of $21.99, sold for a whopping $30.96.
I was tempted to buy another blaster over the weekend, but I decided not to press my luck.
