The concept of a "Shop Basket" would consist on implementing a sort of holding area
where you can pick up items in an NPC shop and buy them in bulk.
The purpose of this concept would be to minimize the appearance of captcha, which has improved tremendously, yet is still a mechanic that makes restocking Merchant Shops tedious. It would also make buying food an easier process, especially for players that prefer to buy in bulk.
I believe Lioden and FR have this mechanic, where you can pick out the items and once you want to purchase, you can just fill out the captcha for all of them.
