Are you sure the seller didn't accidentally ship them upside down? Not sure how they could flip over when packed on a pallet. ( or do you think they fell off the pallet and the shipping company put them back on the pallet? )
If there's no cosmetic issues with the cabinets, I bet you will be ok. But you will want to figure out if you can get replacement boxes in case you ever want to sell them on your end.
