Recently I purchased a couple of rare auto parts from one seller...one for my own project car, and one for resale to a customer. The items arrived today and are excellent, but I almost lost my lunch when I saw the shipping label! This poor guy spent sixty dollars to send a (rather large) 5-pound box from OH to PA. I put the weight and dimensions into the eBay shipping calculator and came up with about $18 for a UPS Ground eBay label. That means this seller gave up over $40 in potential profit just by using the wrong shipping service.
It's clear from the recent rate surcharges that USPS is no longer interested in handling oversize packages, especially at the retail counter. If you want to stay in business, don't do this to yourself! Check all the shipping options, and set up your listings with "standard shipping" so you have flexibility in which services to use. Or if using calculated shipping on large items, be sure it's not defaulting to Priority Mail and showing buyers a crazy quote.
This is not the first time I've seen someone do this, and this guy is a pretty big seller, not an amateur. He must be losing thousands per year to unnecessary shipping charges.
