Some people are just slow and when a family member of friend ships out it can cause problems. I purchased a high end card recently and didn't hear from the seller for 2 weeks, I thought I was screwed out of the card. The seller finally contacted me and told me that his 12 year old son sold the card to me without letting him know and that it would be shipped out the next day.
If he still is contacting occasionally I wouldn't give up yet.
