Hmmm, interesting... I bought Toki Tori for £1.79 and an offer (yeah, it says "offer", not "sale" like the other games) for Toki Tori 2+ came up... the price is now £5.19... I am almost sure it was a little bit higher before that, and the list in OP also shows a higher price. I'm going to buy it now just because of that.
One thing annoys me though. This is the first time I am making a purchase on eShop (or should I say, a purchase worth mentioning - Zombi U, TT, Nano Assault Neo, and Edge just because it was cheap, not having high hopes for that one) and the process is slow as hell. Why is there no goddamn basket? I need to confirm a bunch of thing every time, add funds every time, wait through several loading screens every time. I could understand the general slowness if I could just add all the games I want to buy to a basket first, with no loading or anything, and then go through the process for all the games at once. That would at least be bearable. When it's like this, it literally discourages me from buying more games - this needs to change. You hear me, Nintendo? Change it! You're losing money because of this nonsense!
