Shipping question

I have a guy way down in south Texas who wants to buy a pair of C body fenders. We agreed on a price & I told him the shipping would be too high. He called back & wants me to ship them via Fastnal. I have never done this. Apparently they will ship stuff for 3rd partys on a store to store basis. He said I need to crate them up & take them to my local Fastnal store. Any of you guys had experience with this company ? And what kind of crate? I can get large card board boxes, but the guy in Texas said it needs to be in a wooden crate. I'm all for helping him get the parts he needs, but I just have never done anything like this? Open to sugestions or ideas?
