Just do i understand. If i were to buy a zoa frag, the seller sensds me a tracking number and invoice of the item description and i send money as GOODS?
1. The seller can invoice you or you can send money to seller (just remember to note what you're paying for and send as goods like everyone said.
NOTE: PayPal is not free for seller so some don't like when you pay as goods, they should. If you run into a cheap seller as such, offer half the fee or you can pay for the fee if you want.
1.5. RUN away if the seller only want gift.
2. You pay the seller.
3. The seller (should) notify you with tracking when your item shipped, not always.
4. Cross your fingers and pray so that the correct merchandise come in one piece/alive. Take photos and DO NOT discard packaging item (bag/water/box/foam/bubble wrap..) if the next step is needed.
5. If not satisfied because of seller or shipping company's fault, contact the seller to work out something.
6. If the seller's ignore/refuse to iron out the problem with you then file a claim with PayPal. Expect to ship back the good at YOUR cost and its MUST be traceable (PayPal will not refund you until the seller get their goods (cr@p) back).
PLEASE do a research on seller/product you're buying. Many sellers are not very upfront, they won't point out thing until you ask so please do ask if in doubt, just to save a headache. Not just seller, some buyer can be a PITA as well so don't be that guy, be reasonable.
Sometimes we just have to put trust in humanity and take a leap of faith, with safety harness of course.
Sorry for the long post.
