All prices are in USD. Right from the get-go we decided our prices should be up front and centre because we know we have great prices. From any product page, simply scroll down to the pricing area, where we have a convenient chart of all prices. We typically have over 30 sizes per product. Click on the different aspect ratio categories on the left side of the price list to see all the different size options. Sales taxes are charged based on the tax rate of the delivery destination.
