Lol! It's fine! I was once like that too when I was learning everything. It does seem very daunting, but you will learn it very fast and I am here to help you out! Feel free to send me a private message whenever you need help and I will respond as soon as possible!
I love helping people out since a lot of people helped me out when I first started so I want to give back and help others out too. Did you used to play the old VMK?
Now for the values, sorry for getting off track, lol. The drink me magic is 10,000 credits and there used to be something called giftcards that you bought for 10k and you were able to trade them and sell them for 9.5k credits. People were doing some bad stuff with them (trading them for real money) so they took it away. Now, giftcards are in high demand since they consist of high liquidity (economics term which means they can be converted to money really fast instead of an item). Before giftcards (gcs) were retired, both the minnie bow ears and the green mickey ears sold for around a giftcard. Frozen at the oscars is worth around 7k. Do you have anything else you're trading?
