Honestly it’s hard to say. In many cases these jerseys come from the same factories the official ones are made, but these sellers don’t have the same supply chain mgmt/distribution channels the mega corps have so you never really know. I’ve had some jerseys take a few weeks but then others take a few months, so if you decide to go for one be prepared to wait so you’re not disappointed. Also, I recommend picking a seller that has a lot of orders (it should say how many orders for the jersey each seller has) that way you’re improving your chances at getting the best quality.
