Another nod for Fastenal for me. I used them to ship my last 3 games (1 to someone and 2 to me) with no issues. You have to pick up/drop off at the store and pallet them yourself but I've never paid over $180 yet. There is a store 10 minutes from my house and if the seller/buyer has one within an hour it's well worth the extra work to save $300+
