Looks like I'm not the only one realising that the Megatron toy is not likely to be released on its own (for a lot less than the price of three expensive pairs of shoes), as the prices of the loose figures on ebay are now going way up again.
They bottomed out at just a couple dollars each (after the first few hit over $100), and now I just got outbid on one at $41 with half a day still to go.
(unless it is people here jumping on them after I mentioned it above)
The seller has also suddenly started listing several of them, possibly to capitalise on the renewed interest in this figure.
