Discount code not working

[GreenWatchfulConjure]

So I bought the Twinkly Twelve bundle first not realising that the miner meltdown was just a coupon code for it but now the code isn't even working it just says it's an invalid code, I tried adding an extra "-" because it started with 10 straight characters but that didn't work, I tried entering the code in different places but nothing work and now I need to wait a while to redeem more keys, every other code in the bundle worked except this one and this was the main reason I bought the bundle. Am I doing something wrong or have I been sent the wrong code or what?

I've done the same promotion and it worked for me. You might want to contact support. :/ Sorry to hear that,

One question to OP - did you try to redeem it on Steam? If yes - then that's where your problem originated.
This code for Indie Gala store ONLY! And on the bundle page it say so. So if you want to use it - go to store on this site, find the game, add it to card - and then somehere you can enter this code to get a discount (can't say where exactly - I didn't use mine).
Good luck!
