Has Anyone Actually Gotten Free Socks? What’s the Catch?

I’ve seen those ads too and was tempted, but I never pulled the trigger.
My cousin got some free socks from sockitforme.com and said they were okay.
The shipping was like $6, and the socks were basic but wearable.
If you’re cool with that, go for it.
But honestly, I’d rather spend a few extra bucks and get better quality socks from a store.
Just my two cents!
