Thanks Bunny, I am in the US like the seller.
Ophelia87, she is providing free standard flat rate shipping with no specific delivery date.
This is the second email I sent after no response from the first email. "Hi again. If you changed your mind and can't ship the bag let me know. I can be pretty reasonable. I don't mind getting a refund if something has come up. Otherwise, do send the tracking number if you intend to ship. Thanks."
I called ebay and the CS rep wanted to open the case right away but I wanted to give her to at least today to see if the bag shows up. Also, I'm wondering if something happened to the seller and she's unable to ship since she has great feedback. Life does happen sometimes.
