Before you go make your coffee click on the apply button. Once you have done this you can make coffee and then complete the application. So long as you don’t leave that page or your internet doesn’t drop out you will be able to apply even if 5 others do it at the same time. I normally use another device to thoroughly check out the listing. If you come across anything that then causes you to change your mind you can just close out your application. Hth
