I really can't recommend the store eTail.Market. I bought the game Core Keeper yesterday at 8:30 pm. My order is 15 hours later still pending, although there is a message in the store saying: "You will be able to access your activation code here in an average of 5 minutes to 1 hour.".
Well, this time ended long ago.
I've tried to reach the customer support two times by the website, send a e-mail and tried to send a message by whatsapp, but the number is invalid. I didn't get an answer yet.
I really don't recommend the store, if you want to play the game soon.
Ps.: Got my key at 4pm, so around 19,5h later.
