They have an excellent service system, an advisor helps you search the store's inventory for what you are looking for, you can ask them for recommendations regarding what you need and gives you their opinion. Once you have made the cart and it confirms that they are available. You go to pay cash, when I went I paid in cash, but surely they will have monthly plans. And having the payment done is just waiting for the warehouse staff to prepare your items. There are certain things that you can see (Chairs, Cabinets, peripherals), but there are others that have them saved (SSD, GPU's, CPUs) in short, an excellent store for computer equipment 100 times more convenient than bestbuy, or others competitors.
