In case of non-receipt, you MUST file a complaint with PayPal within 45 days maximum. Do not wait until the last day. Time to file is NOW. It has been long enough.
If the item arrives in the next few days, you can always cancel your claim with PayPal.
Make sure NOT to cancel your complaint until the goods are in your hands and in good condition, regardless of any request or promise from the seller.
there is also the possibility that since the item(s) you ordered are coming from overseas that they could have been held up by customs... I have had that happen to me with some non-ebay orders.
