I suspect there is a range of prices between services, but our service charges $60 ea for couch/loveseat, $50 ea for chair, table, ottoman, small fridge, bookcase; $40 ea for lamp, fan, bike, hockey stick, suitcase, duffle bag; $35 ea for med/large box, rug, plastic tote; $30 ea for small box, poster tube; and $75 redelivery fee. Minimum storage fee is $175.
My kid is fairly frugal, but when you price out storage for bedding, rug, coach, ottoman, fan, lamp, and a few boxes of school supplies, clothes, and other household stuff, plus the redelivery fee, it easily gets into the $700-$800 range, and much much higher for some. I have seen kids with 20 boxes each, plus all the unboxed stuff. In contrast, the storage unit I rented was $50/month with all taxes and fees included. It would have easily fit the stuff of 4-5 kids.
