I wish I could say shipping prices are in the seller's control but sadly, they are not. USPS is still the shipping company that offers the lowest prices and still accommodates eBay with their requirements for "Get it Fast". If you live in the USA we do not charge for shipping. A more speedy option is available through Priority Express which is overnight to many locations but has restrictions and does not arrive in one day to many locations. When choosing this option, please allow for two days if you are in a restricted area. I do not know if eBay is privy to those locations that apply.
With regards to international shipping, if you are seeking a lower cost than the Priority Express Shipping, you may want to check out the "First Class International" shipping option when determining lower costs.
Please be reminded that "First Class" is less expensive but is much slower if you are shipping outside of the USA. If you are in a hurry to receive an item, it is best to do it right away. Calculations produced by the two shipping services can be found by clicking on the "Shipping and payments" tab on the listing.
Also, be reminded that the delivery times posted are only ESTIMATIONS. There is always a risk when purchasing something to be shipped to another country in time for the busiest time of the year or when weather is hindered.
I hope I have helped.
Warmest wishes to you and your loved ones,
