Best place (for Calvin) to buy a Calvin's puzzle?

[Tahrbo]

I'm looking for a Calvin's 3x3x5. Both HK Now Store and Meffert's seem to have official ties to the entire inventory of Calvin's puzzles, but that's purely an assumption on my part.

Would buying that cuboid from one of those places result in more money going to Calvin's than the other? Is one of them more "officially" Calvin's than the other?

Calvin is the owner of HK Now Store. Buying from them is basically buying from him directly.
Also, while I've never ordered from HK Now Store, I have only heard positive things about their service. I can't say the same for Meffert's.

Thanks! HK Now Store it is!

There are no official ties and anyone can sell Calvin's Puzzles. However since he is the manufacturer he would benefit the most if you purchase from him.
