Ebay seller flaking out, how long should I give her before disputing the transaction?

I won an auction on Ebay on July 23rd and paid through paypal (e-check) on the same day. The e-check was taken from my checking account on July 24th and I got the confirmation that it cleared through paypal and was deposited into the sellers account on July 28th.

On the auction it said the seller would ship with in 3 days of receiving the payment so finally on the 3rd day after I got the confirmation from paypal (July 31st), after I got no shipping confirmation or an email or anything from the seller, I finally wrote her and asked her if she could ship out the items I bought. I still didnt hear anything from her, so I emailed her again on Sunday (Aug. 2nd) and again asked her if she could ship out the items I bought and told her that I would be disputing the transaction if I didnt hear from her with in 2 days. She wrote back the next morning (Aug 3rd) and said that she was sorry, her daughter had surgery last week and was not available last week but that she would ship them out either Monday or Tuesday.

I never got a shipping confirmation yesterday, so I wrote her again yesterday evening and tried to be nonchalant and asked that since she said that she was going to be shipping the items on Monday or Tuesday could she please give me the tracking number so I would know when to expect the package and I could make sure someone is here to get it... trying to be subtle by reminding her to ship it... still have not heard anything back from her and for some reason I am not really expecting to hear from her and I am VERY irritated at this point... how much longer should I give her before I dispute the transaction through Ebay and Paypal???
