Shop your list by person, not by store — it's easier to spot who you're overspending or underspending on when the whole list is in front of you at once.
Set a firm ship-by date for anything ordered online and work backward from it; "order by Dec 20" is a good rule of thumb for standard shipping to arrive by Christmas.
Keep receipts and gift notes together as you buy — it makes returns painless and stops you from forgetting who a gift was even meant for by the time wrapping day arrives.
