Really, it just depends on how the seller is feeling at the time.
I might be able to sell you a micro transaction after my BTC - PAYPAL thread goes up, likely in the next 24 hours. You can see the link in my signature.
I sent you a PM earlier and watching your thread. What's considered a micro transaction anyway?
BTW, I really don't pay attention to signatures, but I like that you have your rep thread there. I'm totally going to bite that once I start mine :p
