Talk to the owner. You have brought in how many pounds of stuff over the past few years? Find out how to process the stuff without a deduction. Can you cut up the fridges and then they take them even with the plastic on them? Could be that when they see an intact fridge it is a 50 lb deduction. If not find out what needs to be separated and sell it that way. I put all kinds of small items inside fridges, dishwashers and microwaves to compact the load and save on storage space! Do they deduct for any other plastic or wood items on things or just appliances? And donuts or bottled water for the yard staff may help!
