Can I sue an online tile retailer for the value of tile that arrived damaged?

I ordered ceramic tile from an online retailer. The delivery company called me to set up a time to deliver, but I asked if I could pick it up myself after work from their warehouse, since it is near my home and I didn't want to take time off of work. They said yes. Tile was on a small pallet wrapped with a lot of shrink wrap. I could see no visible damage. When I got it home and opened everything, I discovered that half the tile was damaged. The online retailer told me he would not refund my money because I picked up the tile instead of letting the trucking company deliver it in front of my home. I contacted the trucking company and they would only refund me half the value of the damaged tile. Can I sue the online retailer for the other half of the money? Or is it true, that since I picked up the tile, that the online retailer no longer has any responsibility to help me? They claim to be located in Pennsylvania, and I am in NJ. Thank you.
