From a seller's perspective
The VCR and phone should not have died such a terrible death.
I used to pack things for maximum abuse. You could drop my packages from a second floor balcony without breaking anything. When the shipping prices skyrocketed, I noticed that most of the parts that were my "bread and butter" weren't selling as well anymore. I think it's one thing to pay $7.99 + $3.00 shipping for a replacement handle for grandma's teapot and quite another to pay $7.99 + 5.00 shipping.
I stopped packing most things to withstand maximum damage. So far, virtually everything has arrived intact except for a carbon button microphone with a ring and springs. I made the mistake of shipping it in a flat rate box. When it arrived in pieces, my post mistress told me to never pack anything fragile in a flat rate container because people put really, really, really heavy things in them, and the postal employees just toss them into the truck. Anything fragile, even with reasonable packing, gets annihilated. I also shipped a print sandwiched between two pieces of cardboard marked "Do Not Bend." The mail carrier folded it in half and put it in the buyer's mailbox. Sadly the two items that got ruined were rare and valuable, and I packed them well.
I use less packing on commonplace items that can easily be replaced. It's packed well enough that the carrier will pay an insurance claim, but not so well it can withstand an earthquake. If it's rare, no matter what the cost, I still pack the devil out of it.
I agree on the insanely taped bubble wrap--clear tape is a bad idea to start with, and wrapping stuff in layers and layers of tape is nuts. Sometimes it seems like I'm going to break the item trying to get it free from the tape and bubble wrap. I use masking tape on bubble wrap.
I've always thought the objective feedback choices should include packing quality and should not include shipping costs. A buyer agrees to shipping costs at time of purchase. It seems wrong to give them an opportunity to rate shipping costs that they agreed to. Good packing has always been one of my top priorities.
USPS priority mailing boxes are free (or were the last time I ordered them, and more often than not priority mail costs the same or less with the eBay seller discount. Like my favorite Launderess, I use a lot of Amazon boxes. I get sheets of styrofoam and bubble wrap from the Pier One dumpster and sturdy cardboard boxes from the pet store recycling dumpster. Hills Science Diet boxes are the best--sturdy and available in many sizes. Some newspapers give away or sell cheaply the roll ends of newsprint--not enough left for press, but plenty left for packing. I love it. The result looks very professional.
