shipping guitars?

So, I need to ship three guitars - one acoustic in a soft case, one electric in a soft case, and one acoustic with no case. I assume if I go to the UPS store, they will charge me large sums of money and pack it and ship it. Any suggestions for something not too much more difficult that would be notably cheaper?

I don't think I have any boxes of sufficient size.

I also need to ship an electric keyboard, but that's not nearly so fragile.

Suggestions?

YAY KITTIES

vague apparently *had* a heartworm but the tests to see if she has one now have come back negative. given that she's asymptomatic, i'm just going to start her on heartworm prevention stuff. bonaparte wasn't tested, so i had the vet test her for heartworm before starting her on the prevention stuff.

YAY KITTY IMMUNE SYSTEM!
