Quoted from TractorDoc:

To me, "Fully Restored" would be a complete nut and bolt disassembly, cleaning, art restore, reassembly with new parts as needed -- game is likely as good or better than new.
"Fully Shopped" cold describe a game that has cosmetic flaws but plays/functions 100%. Realistically the potential seller's definition of this can be different -- some totally strip the playfield, some replace the easy to reach rubbers, some wipe the game down with a towel.
