I ordered a coffee table and an end table from Home Decorators Collection --which, I have used in the past, but these tables were very cheap looking, so I chose to return them. Note, I paid about $75 in shipping to get the tables to me -- via UPS, and, they require UPS for return shipments.
I used UPS via online -- for the first time, and had a lot of trouble using their site -- and, the boxes each had a total weight on them, and that is the weight I used for shipping. So, far, I have paid online for the shipments (around $200 total) and UPS has also sent me a separate invoice for $40 -- AND,now gone ahead and charged my credit card an additional $313 --so, I have now spent more than $500 to return less than $500 of table to Home Decorators. I do not know why UPS seems to think it costs 5X the amount to send back the same boxes that were initially shipped to me, but they do. I am working to fight these charges, but they seem to be adamant that these are valid.
I would suggest that NO-ONE use UPS for any shipping unless you want to be robbed.
