But I was using Shop Search....

Screenshot of Search page... I've circled the shop name and url.

Screenshot of "error" message.

Don't know if this is a glitch, per se, but it is an oddity. @ I was able to buy from an alternate shop listed on the same results page.

Very weird! It might have been a slight hiccup. The shop is gone from the search so maybe it resolved itself? Have you encountered it again?

I just checked the shop in question (CLICK) and it's a gallery. I think you just had crazy timing, and the owner happened to switch it from a shop to a gallery.

I have the same problem with another shop. EDIT: It happened more than just once. (with the same one)

This is the only instance of this I have ever found.

Actually, it's a shop again, and I just purchased the Red Small Flats from it via Shop Search.

I don't know why this person would constantly switch from gallery to shop and back, but today I learned that the Shop Search is not always in real time with the status of whether a shop is a shop or a shop is a gallery.

Not sure myself why they would, but it does happen. And yes, there is a timer for how often the shop search updates (and you also have to consider what ends up getting cached).
