Why did the price of shipping change when I added the item to my cart?

When you add an item to your cart the price and shipping shouldn’t change, but there are some rare exceptions:

1. Updated shipping address information

• Shipping prices will vary depending on where you ship an item, so sometimes we’ll need to update the shipping price once we have updated shipping information.
• Some governments also have taxes. We do our best to include taxes up front, but this might change prices and shipping once the shipping address is updated.

2. Changing market conditions over time

• Prices and shipping can change due to market conditions changing throughout the day.  If you’ve been looking at an item for a while or it’s been sitting in your cart for an extended period of time, the price and shipping may increase or decrease.
• Merchants may update their costs, which will change the price and shipping for an item based on supply and demand.
