Pulling items out of a shop, the easy way
You can either go to the shop stock, and click on the "x" next to each item to put it into inventory. This is time consuming, but if you must do it this way, at least click on the "x" over and over. Don't wait for it to refresh, just click it over and over.

Or you can do it the faster way, just buy it from your own shop. If you buy your own item, then you will pay yourself, and it will show up in the history, and the money will be in your till.

This way is faster, especially when you want to take a lot of items out of your shop and put it into your inventory. You don't have to do it this way, but it's faster. Just trying to save you some time.
