It says on their site in FAQ that you can add priority to letters with registered label, but yeah I agree not worth the extra 50c IMO

If a buyer doesn’t pay the additional shipping cost for a 1st Class or Priority Mail bubbled mailer, then I ship the card in a white envelope. I ship several peices of cardboard in the letter with the card in between inside of a sleeve and toploader before shipping. Cardboard is also taped on each side, so the card(s) can’t escape. I also write “DO NOT BEND!” on both the front and back of the the letter. I also COMPLETELY tape the letter shut. I pay $0.70 for each letter I ship because they are shipped NON-MACHINABLE.
I’ve had a few people “claim” that there package didn’t arrive. I basically laugh at them and tell them if it isn’t there yet, then it will be there in a couple of days. It’s impossible to bend or cut the envelopes that I send because of thickness and them being completely taped. The only way to open them is with scizors. There was a guy overseas who kept trying to get me to refund him $40 for a Shaymin Ex, because he thought he was getting two of them. It was clearly stated in the auction title and the the item description that the buyer would ONLY RECEIVE ONE CARD! So then he tried to return it, and I refused. I don’t offer returns under ANY circomstances. I take alot of time making sure that there will be no problems with my transactions. I still have 100% Feedback aswell.
As for the added shipping cost. I take whatever is included in the auction listing. I won’t pay an additional $2 to ship a card to me. It’s always been about the cheapest price in my books. You wouldn’t believe how many cases I have to open on Ebay for a Refund because the card(s) I purchased aren’t in Mint or Near-Mint condition. Probably about one in every three transactions… The only time I pay more for shipping is usually with a big order from AmiAmi, that is over $100. I can’t take risks on something that is atleast that valuable.
So you refuse to give refunds and laugh off people who claim to have not received things, yet open cases and get refunds for yourself?
It is completely impossible for the envelopes I send to be damaged in any way unless they are ran over by a steam roller. They are usually about half an inch thick each. Tons of cardboard surronding the card and toploader. Also like I said they are completely taped Sealed (The ENTIRE envelope with THICK PACKAGING TAPE). People lie about not recieving packages because they expect to get everything for free. What I’ve learned in life is that it is hard to trust anyone because given the right opportunity, you will be stabbed in the back. You wouldn’t believe how many made up stories people give me to try and get a refund. Well, I didn’t receive it, then my dog ate it, my girlfriend took it. It’s a bunch of bullshit. Over cards that are usually around $3-$5 each. I don’t offer refunds period unless you can PROVE to me that you didn’t receive it.

All I’m going to say is that you have a lot of faith in your postal service.

With all that useless protection they’re probably getting destroyed during opening by customs or the end use customer then thrown in the trash.
I used a soft sleeve, a card saver one, one piece of paper, and a long white envelope. That was it and in thousands of mailers I NEVER GOT A SINGLE COMPLAINT.
