I always search by ship to location. Then on AB I sort by newest addition and tag Ecrow only to it. This gives me all newer vendors still new enough to be forced escrow and looking to earn a name.
I find the best new vendors and get some great freebies this way as they always run heavy on weight or other free shit. Found some of my favorite vendors that way.
How bout you? Any tips?
For your primary product(s) of interest, use the [Save Search] and [Restore Search] functions. The former saves the current search (search terms and selected refinements) and the latter obviously restores that at any later point.
