I gifted the money and I did receive my stuff, one tip was floating in the envelope and the other was still in the bag, although the bag had a rip in it (envelope too, but someone patched it with tape).
I honestly believe that it is the poor shipping method that OP used which has caused these issues, and not that he is scamming people. I hope OP and customers who did not receive tips can come to a happy conclusion.
From the seller's perspective, I can see that he is offering these tips below market value (ebay cost) and in order to pass on the savings they are shipped in an economical way (can be improved). Honestly, had I known they were going to be shipped without padding in a regular envelope with no reinforcements I would not have taken the risk.
I hope OP can take this as a lesson learned and perhaps re-send tips to members who have not received them. It may be beneficial in the future to post in the main forum to check what good/safe shipping practices are for tips.
