The only thing I could think of is that the seller did not update their "ship to" location to the dropdown menu selection so they won't be coming up anywhere. I would message SR about it via the "contact us" button on the bottom - specifically which vendors aren't coming up, that way if it's an error in the filter they added they can find the problem faster.SR checks those quite often, more often than the forums. That's something we definitely want to get dealt with.
