Seems like the replica doesn't come with the armor looking ventilation so I guess that would be the price increase.
Also noticed the replica is missing the pink markings on the back.
Unisport customer service is pretty cool. Sent me replacement jerseys free of charge because of the stains. This time they got the printing right even though they said they couldn't in the email. Fine by me though.
I've had a few orders before with no problems. My guess is taking it out of the bags for printing leaves it open to get dirty during the shipping process. Their customer support is good though.
Was excited for these two to show up from Unisport store. Sadly they both came with stains and Anderson came with the unofficial printing despite it saying it had official printing.
Your best bet is to buy the patches and removing the lfp badge.

Other than that I'm guessing checking ebay.
