I have an authentic CCM Alex Tanguay Colorado Avalanche Jersey that I got for $13 + $15 shipping...I have a ton of replica CCM jerseys of teams that cost me about $20-30 including shipping, those retail for about $100 a pop. All jerseys were new with tags. It's all about looking for deals online, with jerseys I would recommend asking for additional pictures before buying if possible.
Pro Tip - If something seems too good to be true, it usually is. I was looking at "Amazing Deals" for winter classic jerseys locally on Craigslist, every single one of them was a fake. VERY GOOD fakes. Fakes that the normal person would not be able to spot, but fakes nonetheless.
Instead of a closet full of knock offs, do yourself a favor and just bite the bullet and spend the extra cash to have a small number of authentics. Trust me, you'll be happier. We all want a deal but so very few of them are decent. Most are total ****.
I just bought two from ECseller.com, a WC and a Cdn Olympic jersey. We'll see what they're like when they get here but so far, people who have bought from there (there's a thread on the main board, too) seem happy with ECseller.
At this point, I should be paid $30.00 to wear a Flyers jersey.
That about sums it up. Why should I pay the outrageous prices they're charging at the Wachovia Center or NHL.com (and don't even get me started on the "quality" of their "replica" jerseys) when I can drop 50 bucks on something 9 out of 10 people won't know is fake? I'm in college, money is tight. A few lose threads are normal for me!
