Next year I hope to finally make it to SDCC (after 4 years, this year I was planning on it, but their stupid ticket system kept crashing each time and I gave up after 6 different attempts).
But even then, I'm not sure if I'll want to spend the entire day in line for something I can get for $30 on eBay. If I go though, I may do the entire show, so by Saturday I may be tired anyways, so wasting a day may not matter. That's sort of a toss-up, and depends on how I'm feeling.
I doubt I'll do the preorder again. I paid $50 to "guarantee" a pink one off eBay, and now they're listing at around $30. So I was stupid on that, but it's alright.
BBTS was the best deal this year, if you ask me. Who knows if they can score it again next year?
And yeah, it depends on what the exclusive item is. If it's ROC2-tied, I probably won't want it, just like I skipped on the Destro 2-pack.
