You received two order confirmation emails and now you're wondering if you have TWO orders!! But no worries!
When you make any changes to your order, or even if you accidentally clicked "Submit" twice, you have not duplicated your order.
Each order submission overwrites the previous one, so you can change your order as many times as you like throughout the ordering period.
Only the last, most recent order is the one that is saved and processed on Sunday evening.
