Free shipping both ways with SA's warranty.Unless you send it to custom shop for mods after the repair,then return shipping is on you.
"Free shipping" on warranty is a fable. Somebody has to pay, and pay a lot for air freight, and it isn't coming out of SA's profits. It just goes into the ledger and appears on the next price increase. I have nothing against taking advantage of "good customer service" on a big item, but for a loose pin? No.
