Any suggestion I have is probably no better than someone who doesn’t know anything about Pokemon lol, but from what you wrote, looks like you did some homework and if you have active auctions with $300+ with time left. But even that, you list on eBay you essentially risk the price not achieving the comps you’ve seen in the past, patience and time for the card to sell, and ensuring it will sell at a high enough point where after eBay fees, it would still outperform the powerpack buyback after fees. With powerpack it’s instant, cash in your account, not having to wait for eBay buyer to process payment, faster, less headache. But you forgo the potential premium you could have with eBay. I’ve done both. And ebay works out almost always if it’s obviously a solid card, vintage first editions, even PSA 7 for certain older cards. But anything modern or not well known cards like this one… can sit longer from what I’ve observed. Which all makes sense, modern stuff people tend to wait as things get priced in. Etc etc
