We are moving out of a 3 bedroom 1300 sq ft apartment that is located on the 3rd floor, we have 3 couches and a love seat, a 4 shelf bookshelf full of books, 2 VERY large concert speakers, a 42 inch flat screen T.V. a king size bed & a full size bed both including frame headboard & foot board, and about 15 large boxes about 7 that are pretty heavy. So we have some strenuous and extremely heavy things to move, that also doesn't include our kitchen table that seats 4, and all of our glass coffee tables, and end tables. The service is 150 bucks for 3 hours, and they will load the truck, follow us to storage and then unload. I have NO clue how to tip these two gentleman, anyone have an idea?
