Suggestions for Discounts on Prepaid Recharges after Jio's Tarrif Hikes

With the recent > 20% hike across Jio prepaid plans, this thread is intended for suggestions for countering/minimizing the price difference:

1) Recharge using MyJio app and pay using Amazon Pay balance. Amazon GVs can be purchased with 5% CB using HDFC Millennia or SBI Cashback CCs

2) Recharge using TataNeu app + Infinity CC and get 5% CB as NeuCoins. However, Value plans are not available in TataNeu app

Dimers, please suggest more ways
