I've been monitoring an important domain via snap names and manually (which seems to have generated better results). The domain was in the middle of its redemption period, so I fully expected to have to wait another 10 or so days before purchase.
The regstrar also had it marked as "REDEMPTION PERIOD" for a couple of weeks, until last Friday, when it was suddenly available for sale.

I immediately purchased it, and received my receipt.

However, the domain has still not been registered (my account panel with the registrar says "pending registration").

Immediately after purchase, the domain was no longer available, and the charge was put on my credit card, but it still hasn't been registered.

I'm going to call them and investigate, but I wanted to see if anyone else has had a similar experience.

That seems a bit odd to me but maybe it got registered at the same time by the person who used to have it?

Let us know how it goes...

I can't find the thread, but someone else had this same issue last week. At first I thought it was the same post, but I see this one was just posted yesterday.
