Transferring back to pc!

Long story short, I want to buy the Complete edition with all the expansion for pc, my big concern is I already own arr hw sb expansion pc version and am Afraid that if I purchase the Complete edition for pc it won't let me register the code in my account because I already own the first 3 expansion? Also not a fan of the idea of buying Sb and EW separately just to play this game on pc because they cost 39 bucks each and the Complete edition is just over 50 bucks, Gas prices is already soaring!, please I need help and enlighten my worries thanks!

If you have just up to Stormblood registered on your PC account, your only option is to just buy the PC Endwalker expansion. You will get both Shadowbringers and Endwalker together with that purchase.

The Complete Edition is only for people who don't own anything for XIV.

The code from Complete Edition will probably work just fine, but it will be a waste of money unless you can get it a heavy discount.
As mentioned, just buy the latest expansion (Endwalker) if you already have the base game. The latest expansion for FFXIV always includes all the older expansions as well.

if you own the base game already (ARR+HW) the complete edition will not work for you.

Thanks for the info fellas!
