I've only ever had one main shop, and seeing as they're doing away with buying items from old shops. I created a new shop, and started putting items into it. So my Silly Question is, can I only autoprice one of my stores a day? Or can I do each shop once a day? (If the feature is even available yet, in the new shops.)

Autopricing in the new shops seems buggy; you might want to check the beta testing thread in the GA forums. I haven't tested it myself. But Autopricing is always one time per day, total, for free.

So its always just been you can autoprice one shop and only one per a day? No matter if you have more than one shop?

Yes. I have 10 shops/galleries and can only autoprice one shop/gallery per day. This has always been the case.

thank you. I've only had 1 shop that I've priced.
