Fairly stupid question honestly. Have shipped many many things after selling them online. However I sold and shipped a racket six weeks ago or so via FedEx and it weighed a little over a pound. Initially paid about $10 to ship and dropped it off at my FedEx. Got a Bill later for additional $10. Seems kind of like a lot for a item that isn’t that large doesn’t weigh that much. I have received rackets via USPS With two medium flat rate boxes taped together and wonder if this is cheaper? Just wondering what people use for reasonable shipping in CONUS. Thanks.
