I read on the news posts that items can be transferred from my old shops to the new ones, but I can't see anything. How can I transfer my items from the old shops to the new ones? TY in advance! :)

Go into your old shop, either select how many of each item you want to move from the dropdowns (or just click to Remove All at the top of the last column) and select one of your new shops from the dropdown at the bottom just above the Process Prices and Removals button

I couldn't see the new shops' names until now, which is why I posted this question in the first place! XD Anyway, thanks for your help! :)
