I'm an apple user, but I use an android emulator to buy ICE this way. It's a little complex but it does save money. Basically, it's like buying a gift card but one that is always discounted. Here's what you have to do: Step 1: Download the Amazon Underground app: https://www.amazon.com/Amazon-com-Amazon-Underground/dp/B004GJDQT8

Step 2: Download Vainglory through Amazon. This is an important step! It may also require you to delete your existing vainglory app.

Step 3: Buy coins. The more coins you buy, the bigger the discount. https://www.amazon.com/gp/aw/d/B0096E8DSM/ref=mp_s_a_1_2?ie=UTF8&qid=1467298940&sr=8-2&pi=SY200_QL40&keywords=amazon+coins&dpPl=1&dpID=418TAh9NMuL&ref=plSrch

Step 4: buy ice in the version of VG you got from the Amazon store.

It should automatically use your coins. I believe that using your coins on ICE gets you 5% back in coins also so that can add up after a while
