How to unlock the Shopaholic achievement in The Witcher 3: Wild Hunt - Definitive Guide
There are 3 items on the block in total with a time limit to raise their price.
You can "change" their price by doing small sidequests right before the auction starts, but in total, you need 1000 crowns to buy them all. At this point in the game, you probably have more than that, but I was not sure if my 10K stack is enough. It was :)
If there is a modification if you skip all the side stuff, please let me know in the comments so I can update the solution.
If you are having problems unlocking this chievo and you are doing everything right, Roosta also reports: I also had problems with getting this achievement to unlock on the GOTY edition. After researching online, I found that resetting the Xbox's system cache and doing the achievement again fixed the problem. To reset the system cache, simply go to the Network section in settings. Go to the advanced options and then clear alternative mac address. This should restart the console and then you should be good to go.
This achievement is obtainable during the quest entitled "Open Sesame!" and is slightly missable. Make sure you have at least 1000 crowns on hand before starting this quest.
Upon arriving to the Borsodis' Auction House, you'll meet up with Vimme Vivaldi and head inside the manor. Make an extra save inside the manor right away. Now travel upstairs with the banker, speak with all three of his acquaintances, and then wait for the auction to finally begin. While seated, Vivaldi will ask you if you plan on bidding for items. Respond affirmatively! If you tell him that you'd rather wait in the back, you'll miss this achievement.
During each item's auction, you will be on a short timer to raise the bid or back out, allowing your opponents to win the item and thus missing this achievement. Always raise the bid against the other buyers! The first item being auctioned is a Brass Eagle figurine. This will set you back 350 crowns. The second item, a portrait of Starry Night Over the Pontar, will only cost 60 crowns. The third and final item in the auction is a rather stylish pair of spectacles that will go for 350 crowns. After winning all three items, the achievement will unlock. If you messed up along the way, make sure to reload the extra save file that you made earlier.
**Missable**
This is part of the main quest "Open Sesame!".
You will need a total of 710 gold to buy all 3 items that are put up for sale on the auction house. When asked to bid, simply keep bidding until you win the item. Your choices are on a timer, so don't take too much time to respond.
This may cost more than 600 coins, you can also ask the banker for another 100, then you will return everything.
I almost failed the achievement because of your hint.
GUYS, WE BUY EVERYTHING!!!!
