I've been noticing that the autopricer won't price my items above at least 7mil - the price shows up on the autopricer page like normal, but once it runs, the price remains at 0sP (or the previous value). Not sure if I'm blind but I don't see mention of a price cap anywhere on the page, so I'm not sure if this is by design or if it's a bug?
There are three steps to autopricing a shop and the third step has two options; autopricer and super autopricer.
Autopricer: Will price items up to 5,000,000 sP. Submitted values over 5,000,000 will be ignored. Super Autopricer: Will autoprice your shop and price items up to 100,000,000 sP. This costs an extra 100 CSC, so use it wisely!
