Eurail continuous passes are on offer for 25% off. On previous deals they were matched by Klook Trave, and a cashback offer. I may be missing something but Klook don't seem to offer the choice of the youth pass or the senior pass, both of which offer up to an additional 10% discount. So if you are eligible for one of those, it may be wiser to stick to the Eurail site. In my case a senior 2 month continuous pass works out to around $15 a day. You don't need a lot of travel to get your value.
Thanks op!
