I have a gold account for a week. How do I use the autopricer? I go to my shop and there's a thing at the bottom that says how much I could potentially earn if I autoprice everything...but I don't see a button for it. I tried clicking on the image of the autopricer at the bottom but I don't think it worked. What do I do?

The third tab at the top of the page should be Autopricer. It goes "Edit Items", "Quick Stock", and then "Autopricer", and then "Profits", "Sales History", etc.

If you click on that it has instructions on how to autoprice, but basically you click the "Load Shop Items" button, which can take a while depending on how much is in your shop, and then make sure the prices are what you want (it defaults to lowest), and then click "submit prices to server" and finally "Autoprice Items in your Shop".

It looks like your only shop is one of the old ones, which can't be priced at all anymore. You'll need to follow this guide to create a new shop to use the autopricer.

Thank you both so much (especially you Darkrai, I didn't realize the shops had updated I must have missed it somehow)

If I update my shop will it get rid of everything in my till? I was half hoping I might be able to get an achievement by earning up enough in there, but I don't want to risk losing points either!

You should be able to transfer your shop till into a new shop. It should be explained in the guide I linked somewhere, but unfortunately I was already done with the acheievements when this change happened so I didn't have to transfer my till and I'm not sure how it works :x

I had this problem myself and got a very informative ticket detailing what to do from . Here's part of it that may help you out.

Thank you both again, I have transferred the items and till over from my old shop to my new one and autopriced the lot! Unfortunately I have lost all my shop till related achievements and they don't seem to be popping up when I visit my till or anything.

Alas.

I filed a ticket. But at least now I'm on the right track! Muchas gracias!
