I ordered a few packages from UK to Israel, all with tracking numbers. Usually it take no longer than two weeks. One of the packages was 3 weeks on "sender prepared the item" status. I was sure it was lost. Spoke to the seller (luckily it was a big website with large stock of the item) so they sent me another one and I received both almost at the same time... 4 weeks for the first, 1 week for the second. I guess there was something wrong with the Royal mail the last two weeks.
