Cannot complete purchase on HP Store

[King_Kan]

I'm trying to buy a new laptop on the HP Store.  The system allows me to sign in with my account.  When it's time to check out, it asks me to sign in (again), at this point, I get the message: Email profile already exists in our system. Please try again with different email.  I don't have another email.  I know that my email exists on their system - I've been using it for years!  It seems like my email SHOULD exist in their system, and that that's a good thing!  What am I missing?

Hi @King_Kan 

Welcome to the HP Support Community. This is a place where HP customers/users post about their HP products and communicate between each other along with volunteers and some HP staff.

I would recommend that you completely clean your browser cache&cookies and try again. Here is how to do it >> https://helpcenter.trendmicro.com/en-us/article/tmka-20816

If the problem persists, you should contact the sales support department. Check this URL and scroll down to the bottom >> https://www.hp.com/us-en/shop/cv/customerservicefaq

You will see phone numbers available. You might also want to chat with an agent (live).

Hope this helps.

Thanks for the advice I've tried all of those suggestion.  In addition I've tried multiple browsers on 3 different PCs, and also the Safari browser on my iPhone.  The issue is exactly the same across all platforms.  The person at HP that I talked to had no idea how to help, but he was able to complete the order for the new laptop.  I may try calling back and trying to get someone else, but for now it's just easier to place orders via telephone, than to waste another half a day with this frustrating issue.
