Next to no one is going to admit to being a sucker, so the 'no' outcome isn't surprising and probably not a true representation of the amount of suckers out there. Add to that, it's just a very small percentage of ESO gamers who use the forums. It's one of the most potent marketing ploys corps etc have at their disposal, so that should tell you more than any poll on here would.
It's a bit similar to those sales most retailers have. 1/2 price. 1/2 of what? 1/2 the price it was when they had it artificially inflated for the 28 days they are bound by law before being allowed state consumers are getting a bargain. A lot of people are easily parted with their cash and they know it, especially if the word 'limited' or the item has a red card next to it.
I find the poll somewhat poorly worded. If there is something I really like, I will buy it immediately especially if it's limited edition. If it's something I kind of like but don't love I probably won't buy it limited edition (like I did not buy the most recent mount even though I liked a lot of things about it because it was weird to have a 2 legged animal). If there's something I like that is not limited, I might put off buying it until I get the urge.
