XAPO is a payment processor AFAIK; they do not sell games. Perhaps you should notify the service selling the games of the price discrepancies.
It's Xapo World. If Xapo World is a separate entity from Xapo, I'm in the wrong spot. But it was promoted upon login to Xapo so I kinda figure they are under the same roof.
what's Xapo World? just curious
Apparently it just launched. It looks like a sales website for downloadable games, with bitcoin the only way to purchase everything. :-)
They might have bigger plans than just games, but that was all I noticed looking through it last night. You should get a pop-up message next time you log into Xapo, at least that's how I ran across it.
