At the moment, with this shop I opened just a few weeks ago, I have marked a specific set of items as SALE
mostly because I haven't yet had time to really sit down and figure out how much they are actually worth... so, it's actually both for customers and for me that I have made a deadline for this sale, so I need to sit down and calculate the real price that will take place after July.
after that, maybe I'm adding a clearance sale section to my shop, for items that maybe have in the future been re-newed several times, so only way they may be selling is lower price. But that will be in the future so I don't know how that works. As a buyer I most likely click the shops Sale section, or if it's shop I visit regularly, the new listings section.
