What % of the UK and US games market does Amazon account for? (roughly)

[MepH]

I saw something on the big GAF September 2014 NPD Thread the other day about it (US Only though). I saved it on a text file but can't find the post anymore, so I'll just copy it there:

"Percentages are based on retailer networks

So when I say "Wal-Mart" I mean:

1) All sales from the 4,311 Wal-Mart stores in the USA
2) All sales from walmart.com
3) All sales from the 621 Sam's Club stores in the USA
4) All sales from samsclub.com

1) Wal-Mart - 20%
2) Toys R Us - 14%
3) Best Buy - 11%
