I’m sorry to hear that this has happened. Unfortunately, I think it
happens to everyone at least once!
Somewhere in or on the packaging there should be a listing of the
actual weight of the package. Take this as well as your
zip code and the zip from where the package shipped and go to UPS to
find out what they charge to ship this package. It sounds as though
the items shipped were also oversized, so you might also want to have
the dimensions of the shipping carton to input as well. Oversized
boxes are charged at a higher rate. Once inputting this info you
should be given the actual shipping charges. If you were charged a
considerable amount more than the actual shipping costs you should
contact the company and try to negotiate a reduction in charges.
If you choose to return the items you will not only have to eat the
original shipping costs, but incur new ones in sending it back. A
company should be able to give you the cost of shipping or at least a
very good estimate before shipping.
I hope this info helps!
