What is the temporary authorization hold on my card?

When you place your order Instacart places a temporary authorization hold for typically 15% higher than your total order at checkout. This authorization hold is placed in case your total is higher due to special requests, added items, replacement items, or weight adjustments. After delivery, the hold will drop off, and your card will be charged for the final total. The final charge will appear within 7 business days after order completion.
