Is there limit to how many items you can have in one? Is there only a certain amount of items in total the autoprice prices? Sorry, been a while since I’ve used my shop^^;

The maximum is 2000 (unique) items for normal accounts and 2500 for GAs - you can see this and how many you already have in Commerce > Your Shops. The autoprice will price everything up to 5m (one per day per shop).

while there is a limit of 2000 (2500) unique items in each shop, there is no limit for total quantity aside from that - e.g. you could have 6000 red balls in your shop and it would still count as one toward the item limit.

and @ Frenchi thank you both for info and cute Ha’s=^u^=
