Same premium tank different price

I'm looking at the store: https://wargaming.net/shop/wot/vehicles/

And I can see some tanks having two prices, but when I open them, they contain the same things.

For example, I'm looking at the T26E4, which I've wanted for a long time, and it's also offered at two price points. What could be the difference, or the reason for this?

Thanks
