I want your guys advice. So I saw a pair of Yeezys on ebay. Purchased them separately through Paypal so the seller could accept my offer. I did not send as gift. The problem is I purchased on Tuesday. He told me that he would send me the tracking the next day. I didnt pay mind to it but its now Saturday and I still have no tracking. He is also not responding to any of my messages. Should I accept that I'm not getting any shoes? I am getting extremely impatient because I sent the money already. All I want is tracking for peace of mind and Its now day 4 since i purchased.
Did the guy have good feedback? Did he remove the shoes from eBay? I'd send him one more message today telling him, you will be filing a claim if you do not receive tracking soon. If he doesn't respond in a week (next Tuesday), I'd file the claim. Occasionally (maybe more like, rarely) there are legitimate circumstances that might cause someone to postpone or delay shipment. However, it is very unprofessional of him to promise a shipping time frame and not update you on any delays. A week from payment should be adequate time, especially if he was responding quickly to your messages before payment. Paypal should have your back, so waiting a few more days shouldn't be bad. It's the weekend now anyways so he can't ship even if he wanted to.
To answer your original question, I would prepare for the case where you won't be getting the shoes though.
Some advice for you and others next time:
1) Ask for tagged and dated pics of the shoe (make sure he has it in hand and is not selling for a friend...etc.)
2) Specify shipment time within the Paypal invoice notes
3) I assume you already did this, but make sure the Paypal invoice (NEVER GIFT) explicitly states: "Adidas Yeezy Boost XXX, Size X, Style Code: XXXXXX, Authentic, Condition: XX." If the seller is hesitant to give any of these details, they are either sloppy and you probably don't want to deal with them or they're trying to scam you.
4) If you go outside of eBay, after you make payment, message the seller to remind them to remove the listing.
5) Make sure seller will double-box the shoes. Sometimes you're dealing with kids who would rather put a label right on the shoe box. You could have them put that it will be double-boxed in the invoice terms as well.
