Rather than buying two shooting star packs, what you should've done was just cop the pair the other guy already got for you and pay the shipping cost since he was giving them to you for retail as a favor to YOU. The rest of what you wrote is complete BS since right after the shooting star packs situation, you were posting in this thread asking people for help copping a pair of Yeezy foams which cost $250 (before any tax). Why would someone on a tight shoe budget be willing to spend $750+ on two releases within the same day? That doesn't sound like someone that puts their responsibilities before their shoe budget, does it?
Let me give you some words of advice. I'm an attorney in my late 30s and collecting sneakers is a small hobby of mine, particularly since I couldn't afford much growing up. As part of my practice, particularly when negotiating a settlement, there has to be some give and take from both sides. The sneaker community is no different. If you want others to look out for you, you have to be willing to do the same for others. You asked others for help in copping the $500 shooting stars pack, which another member was kind enough to secure for you. Rather than trying to save whatever the shipping cost would have been by copping another pack locally, you could've showed your appreciation to that member by fulfilling your end of the deal (a deal only YOU were benefitting from). In turn, that member as I'm sure other members would have been more inclined to help you out in the future.
Judging by your responses, and your apparent dismissal of the favor that member did for you as no big deal, since all he had to do was call and cancel (which we don't even know if he was able to), you show a complete lack of consideration. Maybe it's because of your age, but it's clear to me that you only look out for yourself, and had the roles been reversed, there would be absolutely no way you'd even consider helping another member cop a pair of shoes, especially at retail price.
