So, I know it's only obtainable by having a gold account. But, is there any way to just receive the autopricer? Instead of all of the other perks that are with the GA?

Nope, you have to buy the GA to get the Autopricer.

When you get the GA, where is the button then that autopriceses? (Sorry for dumb question, but I don't seem to remember)

When your in your shop updating prices, it's the last option on the right. It says Autopricer.

I had a hard time finding it too. c:

Ooh alright! Thanks a bunch!! :)
