Shipping to Russia - ebay question??

[GreyMum]

Hi,

I have a potential buyer of a less than 1 lb item. He asked for a shipping quote, so I gave him one for first class international mail (NOT priority). Now, he wants to know when the item would arrive. Any ideas on how to find this out? It is a Christmas item, so I assume that's why he's asking. Any ideas?

Is shipping regular mail, not priority, a bad idea? The cost difference was like 11 something vs. 33 something.
