Question : Flat RAte Boxes from Post Office. Does any one know what the prices are for the different sizes? ?
i know there is a weight limit on them but i don’t know what the weight limit is so do any of you?? thanks so much for any help i’m moving and i figure it might just be cheaper to mail as much as i can in flat rate boxes be for i start paying FedEx huge bucks to ship the rest of it.
can you think of any other catagory i might be able to post this in? usps slightly confused me.
