Oh that sucks, hope your wife is recovered now! We've had a few weeks of illness here too. First my daughter and then it was my turn and I'm personally just recovered.. Hopefully we're good to go for the rest of the winter :)
Let me think about the longest wait, I believe that was for the two coins I ordered from the Royal Spanish mint.. They mentioned on their site that there was a delay in orders but not how long. My order was still being processed a month later and when I contacted them they told me that they were now processing orders from 2 weeks before my order date so another 3 weeks or so was probably going to be added to the wait.
Pretty shitty but at least they arrived at some point.. !LUV
