It is just a slow time right now.
The hobby slows down in the summer.
The lockout hurts the hobby and people do not care as much about hockey at the moment. If training camp was happening then lots of people would be getting into new players. Mark Scheifele was a perfect example last year. He lit it up in training camp and people wanted his cards.
Only high end products; Ultimate, Cup, Prime, Dominion have came out lately. Great cards but quality, not quantity.
eBay lets you list 500 cards for free. You get a lot more traffic on eBay looking for specific cards than in a thread which is very generic and not easy to search.
