Several people here have ordered from black leather jacket and received their jacket and were satisfied. Also, BLJ is just a reseller and you can by the same jackets elsewhere like ebay or amazon if you are more comfortable that way. People just went with BLJ because they were the first to sell.
They often have new Guardians gear for sale before others, even ebay or amazon.
EDIT: I should probably add that these are more budget-minded options. There are some very accurate jackets being worked on here if you can afford it.
Checked around Amazon and FJackeet seems kinda good. Says it a leather jacket and its only like $5 more then the BLJ fake leather jacket Even with shipping its still about $50 cheaper so I think I'll go with FJacket unless people (here) have anything negative to add to it..Saw the pricey $450+ jacket, not really in my range of what I wantto spend.
