[Katsunami]

Diesel has many of the Forgotten Realms books for $4.50 (€3.29) or thereabout, but they also have a lot of them at $7.99 (€5.84). Obviously, I go for the cheaper ones.

Kobo sells most of them for $6.59 (€4.82). If I'd buy them at ebooks.com or the Dutch Kobo store, I'd pay €5.91 and €6.04 respectively. Another source is Feedbooks, at €4.38 for many of them. Amazon is the most expensive: they want to have $9.18 (€6.71) for many of these books if you're outside the US.

Therefore I was quite ticked off when Diesel wouldn't sell me those books anymore, because I'd need to have 30% discount codes at Kobo to match their price. (Of course nobody can match the 75-85% discount codes that Kobo had the last few weeks, causing many of us to raid their store...)

I've also bought the US-only Mistborn trilogy for $2.93 without using any codes. Three books for €2.14 is a very nice deal.
