Oh holy cow o_0 I'd try to find a postal annex if i was you they trend to be a little cheaper...for example i just mailed a mens sz lg shirt from Oregon to new York it only cost me $2.42... I usually do free shipping on anything lighter than a pound. It tends to be under $4 parcel post...just an idea also with free shipping bids will go much higher...
Thank you!! Yes I literally just went through and individually changed each one from free shipping....dang (told you I am new at this- should have done my research)
