go to the shop you want and click Edit Items. on the right side you'll see a remove button. you have to remove each item individually.

how i do it quickly is right-click 'Remove All' on every item for 10 items, close the new tabs, and repeat. also it makes it easier if you narrow down a price range or certain keyword - that way, it doesn't feel like so many items.

all the best love c:

What happens to the items if we delete the shop? Do the items get deleted as well, or do they clog the inventory?

ah yes, i used to hoard stuff in my shop because i assumed that if i deleted my shop, it would just go back to my inventory. turns out i was wrong ahaha :'D all the items get deleted as well, sadly. thanks for bringing it up c:

In the old shops, you can choose a different shop to scoot all your items into now when you delete a shop. (or you can choose to have them deleted and I believe there's an additional warning for that too). I'm not sure how it will work when the new shops come out for everyone, but I do know I saw a Problems & Bugs thread recently where someone deleted the wrong shop by mistake. So that might not be the case anymore in the new shops :x

hehe i made the assumption that people would want the items removed rather than just shifted, so youre right too! and oooh i hope so! it was a pain to remove one at a time xD

OMG -- I love you for saving me so much time! :)

EDIT:

Do you know if there is a problem is I can get items back? I'm going to delete a gallery that has 5k minions -- I simply can't have to go and collect them all again!

- I use the drop down instead of the "remove all" link. If you use the TAB key on your keyboard you can do this kinda fast. So, in the first drop down on the page, select the highest number, then hit TAB 4 times, then press END on your keyboard to go to the bottom of the drop-down.... TAB 4 more times, END, TAB 4 more times, END..... if you do it a bunch, you kinda build up muscle memory & it goes really fast. :)

Thanks all!
