The shipping charges do not only represent the cost of the shipping service, it includes a good protection of the item and using good packaging materials.
But I could consolidate multiple items into one shipment for just a few dollars more, or nothing. It depends of the weight and measure of each product.
We usually consolidate small items whose total weight is equal to or less than 3 lb (1,26 kg), at no additional charge. Even if the total of these kind of products is from 3 lb to less than 7 lb (3,18 kg), the shipping price increase is little, regardless of the number of pieces or if they are listed in fixed price and/or auction style.
Therefore, please contact me to consolidate shipments, it will be a great advantage for your purchases and a very good opportunity to make savings.
Thank you for the preference and trust!
