Am I able to change/add items on an in-store pickup reservation?

Iceberg65

I have already made a reservation to pick up several items for a custom PC build in store, however, after doing some additional research, decided that I want a few different parts than what I originally reserved. I also would like to add a couple additional items on to my in-store pickup reservation as well. Is this something that I am able to do, or would I have to wait until my original order auto-cancels after 3 days and then make a new reservation? I would need to have my 1st pickup reservation cancelled before making another because the 1st order is holding the last unit of a couple different parts on the list.

@Iceberg65 - Don't cancel the reservation. Go in store and get the items you want. Tell them you made a mistake and give them the parts you actually want to buy.
