Unfortunately, 6-7 year old snowboarding gear is virtually worthless unless you're talking about some obscure hard to find item and even then, it's not gonna be worth much.
Throw it on Craigslist locally and hook some kid up. Your price point is gonna have to be pretty close to free. The gear isn't worth the cost of shipping.
