Yeah, all depends on where they end up overall. If the price drops overall or USA sellers continue to have it for $79 with coupons, then if someone has "extras" it's best to sell them when new. But if the sales disappear and the price climbs back up... then smarter to hang on to the ones we got so cheap!
If I didn't have another mod in mind, would have just collected VT133's myself. In your case you like a lot more mods than I do, so you have many different mods, and it makes sense you wouldn't need all the VT133s.
I really don't like ordering good mods from GB or FT. If you have a problem, returning them is a Royal PITA. Vape NW is $100 for Silver and $110 for Black last I checked.
I don't think anyone thinks you were trying to take advantage of anyone, and $100 with a new AS is a good deal. Anyway, if people don't think so, they don't have to buy it. So regardless, you aren't forcing anyone. Plus they sold immed from what I gather, so that tells you it was more than fair. I sold mine for $73 and could have probably gotten more. I also paid for 3-day shipping (nearly $8), and for PP to issue a check, so ended up with less. Again, if I would have known they'd go back up, would have just held on to it.
But that said... don't mind using that as an excuse to get 2 Therion 133s... which I kind of think of as VT133s with a leather and wood makeover.
