i think i'd ask why she wants to wait so long, but surely, come october time the 45 day paypal time limit would be up anyway and if she opens a dispute before hand you'd still have the item ! i don't think it's anything suspicious myself, i would say the risks on her, since if you never sent it she's be out of time with paypal to dispute. or am i missing something ?
maybe she works away part of the year or something.
