Okay, clickbait aside, you do need to do some clicks, copy and paste to get to the stage where you click to redeem makes perfect sense.

For example, in my case, my wife and I, both buy vouchers but with Amex being shit, only stocking Rs. 250 vouchers, I found this hack to redeem them easier than they usually are.

https://www.amazon.in/gp/aw/ya/gcb?ref_=apay_deskhome_AddGiftCard&claimCode=XXXX

Create either a Google Sheet or Excel file, copy the table from Gyftr Email, strip everythnig except the GV themselves, paste the above link a second column and do replace the "XXXX" from it before going further. Then, use CONCAT() function to combine the URL and the GV in another columns.

That's it! You can just visit each URL, when you open the link, the voucher will be redeemed and the page will redirect to the success page.

Do not bother OCRing or Image to text the image above, all vouchers redeemed already.
