I read that each label, especially in ecommerce websites, indicates what users have to do in the next steps, so, terms like continue or something like that, must be avoided. I'm working on a site to order food which is made of 4 steps:
1-choose something to eat 2-login/register 3-choose delivery hours 4-confirm
Each of these steps is in a separate page. The first one, is a page of a restaurant that has some menus or dishes. Users can choose what they want to eat and then proceed to the next step (give personal data - or login). Due to technical reason I can't put the 3rd step (choose delivery hours) before the 2nd one. The problem is, in the restaurant page (1st step), to proceed to the next steps I put a button labelled "go to checkout", but I saw that some people ask me, where can I choose delivery hours? I thought to change the label in "choose delivery hours", but after clicking on it, users are brought on the login/register page. This can be seen as a consistence problem (I said you that you can choose delivery hours, but first I ask you to register or login). What do you think about it? What label do you suggest me?
