Is the Rainbow Slushie a part of any achievement?

there's no easy way to tell. You can't Search Achievements for components, you have to look at them one-by-one.

They are seriously overpriced compared to their usual right now. This could be restockingoverenthusiasticness or false inflation as easily as Achievement fodder though..

[edit] I was restocking there while searching through Achievements and I snagged one. So they are not impossible to get.

I just got one and saw the price and was like ??? I'm also browsing achievos and can't find anything so what on earth lol

Yeah I :"undercut" the current price by quite a bit. Who knows, may be it will sell. :):):)

Maybe someone just wanted a bunch of them for, say, a pet TC and that's why the price is through the roof? There seems to be a bit of a Pride theme going on right now which might contribute to making Rainbow items more popular for display/as gifts.

I remember as a newbie being worried that I would get in trouble for accidentally inflating something that had been dirt cheap and plentiful right off the shop search (what you could price items at capped at 100k at the time mind), a really common and readily available item that I just happened to like enough to want lots of. I still hoard several things I like in bulk, but I try to be more careful these days about not artificially inflating things -_-; even if it's only from 5k to 50k, rather than in the millions (being a skinflint helps).

IMO if you are throwing around that much sP for gifties there are some awesome CWs that are all pride-y and stuff. But Subeta's a pretty cool place and sP here does flow, so maybe what said too.

Sold mine for 2m lol

that was a smart choice. Me, I've been popping in every few hours and dropping the price on mine by a million just to see if there is some kind of demand that we don't know about. So far no bites, although some vendors are no longer in the list so some users are buying them. Now there's a chain of unsold ones priced less than the 15M you and I saw original.
