Hello, thanks for waiting and welcome to eBay Live Help! My name is Frances. How may I help you?

Hi Frances! Thanks for your help! Here's the issue: Many potential buyers have contacted me in regards to my current listings. Some are receiving exact shipping quotes via eBay (1 - 2 lbs), whereas others are receiving quotes for $20 - $40! (yikes!). What is causing this issue/error?
1:37:43 PM Frances S.
I appreciate you contacting us about this. I'll be happy to assist you with that!
1:37:49 PM cobra.island.arms.dealer
Great! Thank You!

1:40:25 PM cobra.island.arms.dealer
Thanks, Frances!!! I really appreciate your help!
1:43:33 PM Frances S.
Thank you for staying with me.
1:43:46 PM cobra.island.arms.dealer
Oh, no problem! You're the one doing all the work!
1:45:37 PM Frances S.
Just to clarify, since this is a calculated listing, your buyers may come from different locations. Are they aware they will get different shipping costs?
1:46:05 PM cobra.island.arms.dealer
yes, they are.
1:46:11 PM cobra.island.arms.dealer
thing is, they're shipping to the U.S.
1:46:17 PM cobra.island.arms.dealer
shipping shouldn't be more than roughtly $8 & change
1:46:35 PM cobra.island.arms.dealer
some people have gotten quotes from Michigan to Ohio (one state away) as high as $38.
1:47:17 PM Frances S.
Wow, that is really high.
1:48:01 PM cobra.island.arms.dealer
Agreed

That's why I was pretty nervous, because I don't want anyone to think I'm trying to gouge on shipping, nor do I want my listings cancelled due to fraudulent shipping charges.
1:49:33 PM cobra.island.arms.dealer
Each listing was set at Priority Mail Service, 1 - 2 lbs shipping, plus $1 for handling. At the most, I think the highest rate would be to California, which would be around $8.90 (well, $7.90 + handling)
1:51:32 PM Frances S.
We have heard that some are having discrepancies with the shipping cost. we are working to resolve it as quickly as possible . The best way I can suggest to you is to contact the buyer and tell them that you may just adjust the shipping cost in the invoice you will be giving them.
1:52:06 PM cobra.island.arms.dealer
Sounds like a plan. I've also added a disclaimer to each listing advising that shipping would not be anywhere near that high amount. Hopefully people still have trust in the world!
1:52:17 PM cobra.island.arms.dealer
On that note, thanks for your help, Frances. It's greatly appreciated! Have a great afternoon!
1:53:07 PM Frances S.
Have a great afternoon as well. You are actually doing the right thing on these items. I wish you all the best with this listing and with all your future eBay transactions! Is there anything else I can help you with?
1:53:20 PM cobra.island.arms.dealer
No, you've been great! Thanks again for your help!!
