Had a good track record with my shipping also. Just lately, in the past few months, have had shipping/damage issues, that I cant figure out. Still dealing with these issues, and don’t want to cast aspersions on the buyers till the issues are resolved. I will post my interactions here after resolution, to get feedback. In the meantime, I will look to add more cardboard to my shipments. The funny thing is I actually try to discourage the ‘picky’ buyer from bidding by stating defects/pics, with statements like ‘DO NOT BID IF …’, and describe the shipping method, but still get comments about condition. BTW, no problem with someone being ‘picky’, as long as they understand and I make clear that I am not, and will not be, about minor imperfections.
Most if not all of my listings might mention something like… “This book appears to be in NM, could be NM+, could be NM- but judge yourself from the pics, as the actual grade is not guaranteed as I’m not a professional grader. I can just claim the book arrives in the same condition it leaves my hands.”
Never had anyone come back and try to lay a claim not meeting their expectations.
And books with flaws, I always snap pics of the flaws and point them out in the description.
I only tape the incentive ratios over $20 or so in price, or higher price comics to cardboard to dissuade bending. Other than that, I take the risk of someone taking my gemini and folding it in half…I do put fragile and do not bend stickers, and i have packaging tape that looks somewhat professional to hopefully tell the postman, hey, this guy is trying to send out a good product, don’t mess it up!
I’m going to knock on wood, but I have a very low return / damage rate with my system so far, and I’ve shipped a few thousand comics (if not more) out at this point. I’m talking maybe 1 or 2 damages. I price my shipping at $5.95 initially for First class, and .25 cents a comic to combine. After 4 comics I’m at $6.95, and its $7.70 for a Legal Flat Rate Envelope…so i usually eat the .75 cents and give them a faster shipping option since they bought more than 1 or 2 comics.
The forum actually turned me away from media mail… 1. because its illegal, and 2. because it stays in the mail system longer. At this point I’ve seen higher sales since I upped the rate, an opposite effect I thought was going to happen.
Good luck and please let me know if I can help any in the future. I don’t mind sharing my “secrets” 
I do not list a grade, but try as best as I can, in bold, large red lettering with pics to describe the defects. I ask buyers to judge for themselves, and request more pics, info BUT still … It is frustrating. Also, to be fair, Ebay has sided with me so far on many disputes, so no issues with Ebay per se, just these ‘few’ buyers. Again, for the cases that bother me, I dont want to judge the buyer prematurely; would prefer to get feedback later on. I accept that I could be in the wrong in some cases … Just the price of doing business, sight somewhat unseen.
I hope I am not derailing this topic !
Also, for the most part USPS has been good. Had a few of the long delivery problems last year during the height of COVID, but these were understandable. Even the buyers were understanding. Maybe I have undiagnosed OCD, but even one problem is something that bothers me, as I take pride in being fair to customers.
Actually, for a period of time, things I’d ship out media mail were taking 3-5 days while my priority packages were taking up to 2 weeks at times.
But yes, if you’re sending out hundreds or more packages a week, my entire process would change. I would cut corners and take more risks, particularly for the lower cover price books. The amount of effort spent on books that are $4 do not need me to spend $1 or more on packaging while also spending the extra 5 to 10 minutes just to pack them like the higher value books.
If you want proof my system works, this is a feedback I JUST received. Talk about a big win!
“Package came sealed in a plastic bag with an apology from the USPS with it appearing to have been completely submerged in water. Label was BARELY legible so I’m not sure how they even delivered it this way. The comics were packaged so well though that they were not damaged and no water actually got to the comics. The box and outer envelope were soaked. Great packaging!!”
Made my day!
This gave me a chuckle
That’s a really high grade, and is a great book! I have one but it’s maybe a 2.0 or 3. I also have his first number 1 title too.
Well looking at it closer its definitely way over graded lol.
I seeeeeeeeeeeeee now! Wow! Thats more like a 6! Must be a trainee!
No, that’s typical of the CGC seasoned vets they got over there grading comics… 
“Today, CGC is the world’s largest and most trusted third-party grading service for comics”
Well - they are the largest. They got that part right.
That book isn’t even close to a 9.6. Yet those idiots keep adding new things to grade when they can’t keep up with just comics. I also don’t like that they grade older books differently than moderns. All books should be graded the same regardless of how old they are.
I just tow the line now.
Everyone seems to want cgc. It’s cgc cgc cgc because of the monetary returns. Money talks. Money is power
One big giant incompetent pyramid scheme but it makes me a whole lot of money so I hope everyone keeps buying into the pyramid scheme
Not a headache…this is something new I just discovered.
If you have an Ebay store, Ebay lets you create & print COUPONS to send to buyers.
That’s interesting about the coupons. My big problem is the lowball offers I get on books I list. I don’t like to put a minimum offer in so it’s partly my own fault. For example, I have a book listed at $79.99 right now I got three offers, one at $55 (which isn’t terrible but I am not knocking off 33%) one at $40, and one at $25. I told the $25 guy to pound sand and blocked him. People try to make their own coupons sometimes.
Haha! Great! I remember I received my Iron Man 55 in a plastic bag from usps and the entire cardboard mailer was covered in some sort of dried black ink that was flaking off.
Mercifully, nothing actually made it inside the package. Had to open that one in the garage over a bucket.
You should use the auto-decline feature so you don’t have to even waste a second of your life to look at/respond to ridiculous lowball offers.
