[Altitude Sports] $15 off all items before April 13 purchasing a $30 credit for $15 charitable donation

Essentially a $15 coupon. Create account, purchase a "donation" and immediately receive a $30 credit into your account for use. Free shipping over $50. For example, I purchased a Black Diamond Sport 400 headlamp priced at $50.99 on sale that had an additional $2.50 off (5% member discount) for a total of around $48.5 and received 2 day free Fedex shipping. Final cost to me is around $33 before taxes. Might be useful to some. Prices are on the high side but you might find an item of interest at a good price on sale.
