It was a $90 set and has been avail at <$45 for many months. There's 200+ sellers on Amazon now, and I bet a lot of folks who snagged these at $30 at Target/Walmart. Would you LOSE money at $40 on this, no, probably not - but I expect it will take a very long time to get to even break-even.
Compare it to the Mechdragon which saw similar pricing and availability, and it's been retired over a year and is still avail for $65 on Amazon. May take another year to get close to MSRP.
So, if you want it as a build/gift, $41 for a $90 lego set is solid. If you want it for investment, I'd stay far far far away until the price gets to $30. And even then I'd be hesitant.
Many Wave 1 Chima sets (retired approaching 2 years) are just now seeing their prices creep to MSRP, and only a few of the sets out of the line have shown gains at all. I'd strongly encourage you to put your investing dollars elsewhere. Really, that goes for the whole Chima line. Unless you're buying in at 66% off or more, I'd avoid.
