CS: Go how to sell multiple cases?
Do you want to finally learn how to sell all the CS:GO crates and other items? If so, let’s get started. First, it should be mentioned that in reality, the Steam community market has had its own wholesale sales feature for a long time, and we can directly place a large number of CS:GO items in our inventory on the Steam community market. Remember that not all CS:GO items can be sold. We can sell crates, capsules, stickers, keys, passes, etc. However, weapon skins and agent skins cannot be sold. Additionally, items that are more than $1 will require mobile phone verification.

How to Sell All CS:GO Crates?
In this tutorial, you will learn how to sell a large number of CS:GO items, such as weapon crates, through the bulk listing feature available on the Steam community market.
Steam Inventory Helper The first and easiest way is the Chrome plugin Steam Inventory Helper. This plugin has one small flaw… That is, “you select items,” then click “sell selected,” and enter a price. At this point, there is a small problem, you have to click the confirmation button as many times as you want to sell items. Something safer and simpler would be useful. Does Steam really not have such an option?
Gaben’s Secret
The next method is called “Gaben’s Secret.” This method is hidden by ancient CS priests from young adepts. Interestingly, the usage method is very simple, just edit the link to the wholesale sales page of a specific item:
https://steamcommunity.com/market/multisell?appid=730&contextid=2&items[]=XXXX
The above link is a collective link for Steam selling CS:GO items. Items[] is followed by XXXX, which is the English URL character for CS:GO. For example, if we want to sell a Prisma 2 weapon case, open the Steam market page for the Prisma 2 weapon case in your browser:
https://steamcommunity.com/market/listings/730/Prisma%202%20Case
Add “Prisma%202%20Case” after &items[]= to the collective link to get:
https://steamcommunity.com/market/multisell?appid=730&contextid=2&items[]=Prisma%202%20Case
Enter the quantity in the field, then check the box to accept the “Steam Subscriber Agreement,” and finally click the “Create Auction” button to start the automatic bulk listing. If the quantity is large, it will take a little time (even several minutes). Furthermore, items that are more than 1 USD still require mobile phone verification.
Summary
Finally, something for advanced users. The Steam wholesale sales page can also handle many items. We just need to add “&items[]=XXX” to the link a few times. For example, if all weapon crates are standardized on the wholesale sales page, the link may look like this:
https://steamcommunity.com/market/multisell?appid=730&contextid=2&items[]=eSports%202013%20Case&items[]=Operation%20Bravo%20Case&items[]=CS%3AGO%20Weapon%20Case%202&items[]=eSports%202013%20Winter%20Case&items[]=Winter%20Offensive%20Weapon%20Case&items[]=CS%3AGO%20Weapon%20Case%203&items[]=Operation%20Phoenix%20Weapon%20Case&items[]=Huntsman%20Weapon%20Case&items[]=Operation%20Breakout%20Weapon%20Case&items[]=eSports%202014%20Summer%20Case&items[]=Spectrum%20Case&items[]=Operation%20Hydra%20Case&items[]=Spectrum%202%20Case&items[]=Clutch%20Case&items[]=Horizon%20Case&items[]=Danger%20Zone%20Case&items[]=Prisma%20Case&items[]=Shattered%20Web%20Case&items[]=Prisma%202%20Case&items[]=Fracture%20Caseost=36253&action=edit
Remember that we can save a website or URL using a web browser and use ready-made templates in the future.
