Ebay can be the perfect place to shop if you want a good bargain.
I bought both the 3DS and Vita from Ebay. Both were incredible deals.
Vita came with two games and a 4GB memory card and because I bid right at the last moment in the auction, I got it all for about £100. I then ended up selling one of the games (COD Declassified) for £25 lol.
You just got to be a little patient.
