Knockoff jersey stores are prevalent online. The only thing you save is money when you purchase from a fake NFL jersey site. Fake NFL jerseys are often poor imposters that may take weeks to receive in the mail and are known to fall apart, have crooked lettering and worse. If you go to view a product on a jersey knockoff site, there will likely be no alternate views of the jersey to see its quality or authenticity. The description of the jersey may say it features sewn-on lettering, while the picture of the product shows screen printed letters. There are often times the web page will feature the wrong colors as well, not the authentic team colors for that NFL team. There are many ways to get a cheap jersey online, but if you're looking for quality and authenticity, it's good practice not to buy from knockoff sites.
