A lot of stores tend to just get rid of old stock after a while if nobody buys it even at rock bottom prices, so they may have sent it back to a distributor or something, then Target thought "oh, we should take those" since then if anybody wants it, they'll have to go to them.
Some of my local stores do stuff like this, where if they have sale stuff out, after so long of it not selling, it just disappears. I remember asking once in Tesco (might have been somewhere else, but I think it was Tesco) about some games I'd seen on their sale shelf a few days before (and I'm talking,
multiple copies of these games, so not like someone just came in and bought the last one of each) and they said that as they'd been out so long (on display) and nobody wanted them, they returned them (so they couldn't just go into the stockroom to get them for me).
And obviously when things go back to distributors or whatever, they will want to sell them to somewhere else, to make money, rather than just destroy them, therefore other stores can then purchase the old stock.
Similar to how sometimes something can be listed as a store exclusive, then after like a year or so, other shops have them for sale - DVD and Bluray "Reel Heroes" line (has comic art style covers) were exclusive to HMV here, and had been for aaaages, then one day, HMV no longer had the "HMV Exclusive" stickers on them, and barely had any stock (despite having millions beforehand) and they were now available in like Asda and Tesco!
So it seems that Target just bought up all of the old stock of Kid Icarus maybe, rather than just a percentage of it
WHOA, sorry for the novel! xx
