Winter is coming, and you need winter clothes shipped to Israel - or any country outside of the US and Europe. Shipping from Amazon is either expensive or impossible, as many sellers don't ship clothes to Israel. They do ship smaller things, like cd's, which I've bought on both Amazon and eBay.
Head over to eBay. Filter yourself the nicest sweaters by Brand, New With Tags and Buy Now. Be one of the only Israelis wearing Hot Sox. Same goes for sweatpants/pajamas. For only a few dollars, you can get winter socks from top brands.
Search by "price + shipping". Many more sellers ship to Israel for either free or a low price - you have a lot more choice here as opposed to Amazon when it comes to clothes.
There is always a seller with low shipping costs willing to sell quality items on eBay.
Winter clothes shopping isn't something associated with Israel, and going international is the only way to go!
