I personally don't see many people wearing NFL jerseys in the streets. I think the primary reason is because of the general look of some of the jerseys. Never the less, there are many jerseys out there that people can get for cheap. If you search hard enough, you can find wholesale jerseys for pennies on the dollar. I am going to help you find some of these jerseys. Most of my resources are online. It can get difficult to find merchandise offline unless you have someone you know personally who has access to a particular item.
The first thing that you need to determine what type of jersey you want. Are you looking for throw back jerseys, New jerseys, or a particular player's jerseys? You need to find out what type of jersey you are looking for so that you can narrow down your search. If you are too broad with your search, then you might spin your wheels. This is not the way you want to search for an item. Once you find out what you are looking for, then you will be able to effectively find out how much you are willing to spend on the jersey.
The one place online that I will say you can find wholesale jerseys is on eBay. I know that this place is typical and cliché, but it is the best place to find wholesale items because of the bidding method. If you pay attention to the bids that are involved, I'm sure that you can find NFL jerseys at wholesale prices.
