I know.
We track all sales and interest through the VGChartz Amazon store (which also helps provide income for the site, so buy here instead of amazon 
) Other than that, there are no direct numbers from online stores that I'm aware of.
Also, they track them just like they track all other stores they don't get direct numbers for. For example, ioi may not get actual sales figures from ToysRus, and they have some really good deals (buy 2 get 1 free), but they are included in the figures by extrapolating what he does recieve to cover the whole market.
So the figures on the site aren't "forgetting" any sales from any store, be it online or physical retail store.
