Your thread should be on the marketplace and not on Bitcoin discussion, in my opinion.
You can also just add up your comment to the thread instead of that expansion; by posting in a role you are violating the forum rule number 32.
Agree on #1 and also would tell OP in plainer language that bumping one's own thread isn't allowed more than once per 24 hours and I do believe previous bumps need to be deleted (or at least it's good forum etiquette).
Aside from all of that, I give major props to OP for this:
Fuck ebay and their 25%+ fees.
Hate to say it, but nowadays the fees aren't even the absolute worst of their business practices and their site and how they treat sellers is so different from how it was back in 2000 that young people wouldn't even believe how easy it was to buy and sell on ebay years ago. It was like an internet flea market.
And now? Sellers are urged to pay to promote their items for outrageous percentages and all sorts of other shady shit. Good luck to you, man. If I collected graded cards I would throw some business your way...but I don't. I'm hoping some collectors see this and do buy from you. Just move this thread to the Marketplace section (pretty sure that's the best match, but others may have better suggestions). Anything but ebay!
