If the price and condition are the same, I would definitely buy from Yoogi's. Tradesy is all individual sellers, much like eBay, and I am not sure how their return policy works, which could be very important if you end up getting a fake. They guarantee authenticity, but I do not know how many hoops you have to jump through for a return. Yoogi's is a well-established company with a 30-day free return policy, for any reason, as long as you do not remove their tag. If you choose to buy on Tradesy, I would make sure to get the item authenticated first.
