I was looking at some car audio (of which a lot is on sale, and says free registered shipping too!)
When I saw the donate link.
I thought, sure, red cross is 100% not a scam, I'll throw $5, when I saw this offer.
Anyone doing anyhting with audio or the like, might find a 'free $5 off' while helping a charity (so, tax claimable!) welcoming.
Could I just donate $5 worth of blood?
