I've Bought an iPhone 4 off eBay?

I've paid for it but the phone has not been shipped yet. It's been 3 days since I've paid for it. Should I worry!
What should I do?

Added (1). In the email that came after buying the phone, It said that it should be delivered by Thursday! But on the page it says "not shipped" and she has logged on because I've message her about it.

It depends on the approximate shipping time stated on their website. I don't think you should worry for now but if you do not receive it within a week, then that is something to worry about

Could you post the link to the ebay listing?

Give the seller chance, you bought the phone Friday & today is Monday. Perhaps they shipped it today but haven't had chance to log onto Ebay to mark the item as dispatched yet.

What is the shipping policy as stated on the auction? Some sellers state that they ship within "7 business days" or even 10 business days. This doesn't include weekends. You could just message the seller & ask them when they expect to post the item. I do hope it is being sent by registered "signed for" delivery?

Then wait till Thursday before you start worrying (you have 45 days to claim INR)
AND it dosent matter if its coming registered/recorded/tracked (as has been suggested) the seller will be responsible to get it to you or lose a claim
Tracking is for a sellers benefit

3 days or 3 business days?

Remember that most companies are closed on the weekend, and Monday was a postal holiday. Also, eBay has a tendency to overpromise on shipping time. Amazon tells you the handling time and the estimated delivery date… EBay just guesses based on the handling time and seems to think the item will be teleported.
