Description from store Fight Scalpers with Power. Costbell is a fully automated bot that helps you shop highly in-demand products, such as Xbox Series S (XSX), Xbox Series X (XSX), and PS5. This tool automatically checks the inventory on the merchant website and purchase the item for you as soon as the product is back in stock. Features: - AUTO INVENTORY CHECK / PAGE REFRESH - We will automatically refresh the product page and check the inventory for you, so you can spend life on more meaningful stuff. - AUTO CHECKOUT / PLACE ORDER - As soon as we detect the item is back in stock, we will try to checkout and complete the purchase for you, so you can have a sound sleep at night and leave the heavy-lifting to us. - AUTO CART ERROR HANDLING - We will gracefully handle the situation if the item went out of stock while in the shopping cart, just like an actual human. - AUTO CVV ENTERING - If the merchant requires credit card CVV at checkout, you can store your card CVV on the Settings page, and we will automatically fill it for you. - AUTO LOGIN - If for any reason the merchant asks you to login again to complete the purchase, our bot will log you in automatically so you won't miss any buying opportunity. - BROWSER NOTIFICATIONS - We will send you browser notifications when we have the item in the cart or successfully made the purchase, so you are always informed of the good news. - EMAIL NOTIFICATIONS - We will send you email notifications if we've successfully purchased your item, so you always stay in the loop of what's going on without having to be around your computer.
