On my e-commerce site we have a subscription page where a user fills in their information (name, address, phone number, etc.) and hits subscribe to receive our catalog. If the user is already logged in it is possible for us to simply fill in the fields with the default shipping address and other information that we have on file and they control from their account panel. However, I'm having difficulty deciding if I should make this the default action or if I should just let all users fill it in manually.
Pros:
- For users with that data already entered they won't have to enter it again, saving time
Cons:
- It is entirely possible a user wants to ship these catalogs to a different address than their default (although I'd wager this is less often the case) so deleting our autofill and filling it out again would double their effort
For users without data on file nothing will change, they will just fill it in manually.
