Is there a way to change/correct Calculated Shipping Weight and Parcel sizes?

[agvkrioni]

I'm selling parts from my PC that died. I sold one part already and the calculated shipping charged the buyer around $6 for shipping when the actual cost (the cheapest cost available at the post office) was around $11. I went to the other listing I have and checked out the calculated shipping and for example, I saw one item that the manufacturer's website says is 3.5lbs in weight, but ebay lists its weight at 3lbs. I also can not change the box/parcel dimensions either. I want to sell all of my items but I can't get shafted on shipping on each one. Either I have to raise prices or find some alternate method of calculating shipping. The problem is the buyer could end up being anywhere in the continental US, I might say a flat rate of $10 and it could be $15-$20, or the buyer might be in a state nearby and end up overpaying. I am really frustrated right now. Is there anything I can do?

You need to use Calculated shipping, based on the prepackaged weight & dimensions.

Here's how to use calculated shipping when listing your items:

1. In the Shipping section of your listing, select Calculated: Cost varies by buyer location.
2. Next to Services, select Calculate Shipping.
3. In Package details in the Shipping Calculator, enter your package type, dimensions, and weight. 
4. In the Your details section, enter your ZIP code and any handling fees.
5. Select Calculate shipping.
6. Select the shipping services you want to offer, and drag them into the order you want buyers to see them.
7. Select Offer shipping services.
8. Complete your listing.

So it IS possible. I didn't check the information when I created the listing so I probably have to recreate the listing from scratch to modify that information. Thank you.
