To make it simple, you have 2 options,
1. Know somebody/somehow and hopefully they will give/sell you know.
2. Get a part job with Nike, then you would have unlimited access to the ES.
FYI, using the "VETS" card may not be your best bet, hoping people would give/sell because your a VET. Nike employee's get a total of 5 thought the year, they usually get bonus ones thought out the year, so for someone to just give one because your a "VET", not likely...
Not trying to bash/be mean, just telling you the truth, I know this cause I am a current employee.
Good luck, hopefully you will get in.
