Glad you found it informative @silversaver888 :)
It's really worth to use it, because of the site (easy to use, nice overview , fast) but also double cashbacks from Monstermarket and in case of packs from Steemmonsters account as well.. More savings OR more to spend lol :)
I have ignored the Monstermarket for quite a while as they used discord bot to buy the cards, I hate that, it's not my thing. When I found out about the site, it was a no brainer :)
I am not computer savvy... and I just couldn't get my Keychain something... ARRRRGH!!!!
So tell me, what went wrong? Did you follow the links in the post to get the extension? Relax, it's easy peasy so no worries, everything is going to be fine!
