Angie:
I'm a tad confused...did you transfer the money to your bank account or are you waiting for an e-check to be processed?
If you sold something on ebay and the payment was processed through Paypal, go to your ebay page...it will tell you whether or not the payment was processed and you are good to ship the package.
You can also go to Paypal - not via any e-mail - but open a new tab - and go to paypal.com and see the status of the payment there. If it is processed and in your Paypal account, then ship it.
If they paid via e-check - it will show that it is still processing....and you will receive a notification from Paypal that the payment was successful and that the package is now okay to send.
If you are transferring what they paid you to your account - then they should not have to wait for that transfer to take place.
Please feel free to Inbox me with any questions you have...
IF by chance the buyer is NOT happy with the purchase and wants a refund - go to THAT transaction and then click on "refund" where you can refund one penny to the whole amount - doing it this way will get you some or all of the fees associated with that transaction refunded to you.
You CANNOT give them back more than they paid you - so if they want to return the item and you have stated you will pay return shipping, you can refund them their money, via their transaction and get all of your fees back and then "send" them money...
The shipping calculator is in the same place you post how much shipping is - flat rate (same to all customers) or via postal code - if you check postal code - then THEY have to put in their zip code..YOU put in the weight and the measurements of the box.
Try TurboLister instead of using the "sell now" button if you have more than 10 things to list - makes your life MUCH easier!!
EDIT:
Angie - if you requested a signature - then you mailed it with insurance...that's more expensive...paypal and ebay will accept the delivery confirmation transaction number should there be a dispute on whether or not it was shipped.
